What does rounding mean?

"Rounding" means rounding the digits after the decimal point, i.e. rounding off if the first digit of the rounded part is less than five; If it is greater than or equal to five, the last digit of the reserved part is added to 1.

Pronunciation: [ sì shě wǔ rù ].

Sentence formation: 1If the number is equal to or higher than 5, it is rounded to the nearest ten digit.

2.I like you at first sight, I pursue you twice and three times, I round you off, I cherish you, the six gods have no owner only for you, I miss you seven up and eight times, 912 nine (just) want to love you, very happy to promise me!

Rounding is a method of counting retention with precision that is essentially the same as other methods. However, the peculiarity is that rounding is used so that the difference between the reserved part and the actual value does not exceed one-half of the last order of magnitude. If the probability of 0 9 occurs, the sum of the errors of this retention method is the smallest for a large amount of retained data.

That's probably why we use this method as the basic retention method.

The so-called rounding method is a method of taking an approximate value when calculating, as the name suggests, the smaller than four (including four) should be discarded, and the five largest (including five) should be advanced by one place. For example, if one decimal place is required, then it should be rounded off according to rounding, that is; For another example, if one decimal place is required, then according to rounding, it should be advanced by one digit, that is.

When taking the decimal approximation, if the highest digit of the mantissa is 4 or less than 4, remove the mantissa number. If the highest digit of the mantissa is 5 or greater than 5, round the mantissa to the position before it"1"This method of approximating numbers is called rounding.

Rounding the lower digit below five (excluding 5) and above five to the highest, e.g., rounding one digit after the decimal point becomes 2 if the whole number is rounded

There is no trouble, it is a number of "single digits" (such as 55, 56, 57, 58, 59) greater than or equal to 5 to 1, the same is 60. If the "single digit" is less than or equal to 4 (e.g. 84, 83, 82, 81, 80), it will be removed, and it will be 80. The most troublesome thing to define is to understand the main thing.

It refers to the method of taking an approximate value, which is generally greater than or equal to half of the unit into 1 unit, and less than half of the mantissa is rounded off to zero. For example,

Rounding is a method of counting and retaining accuracy, with a difference of no more than one-half of the last digit.

What is rounding?

What is rounding and how is it calculated?

Rounding to the single digit is to get the number and keep the whole number; Rounding to ten places means that the number is retained, and the whole number is retained; Rounded to.

Hundreds, thousands, and tens of thousands are reserved for hundreds, thousands, and thousands, respectively.

1. Rounding to a single digit means that a number is accurate to a single digit, omitting the decimal part and retaining the integer part. When the value of the decimal digit is greater than or equal to 5, the single digit value is moved to 1, and the decimal part is omitted. When the value of the decile is less than 5, the decimal part is omitted.

For example: Rounded to the nearest unit. Fight the rules.

Rounded to the nearest unit.

2. Rounding to ten digits means that a number is accurate to ten digits, and the part after ten digits is omitted. When the value of the single digit is greater than or equal to 5, the value of the ten digit is advanced to 1, and then the part after the ten digit is omitted. When the value of the single digit is less than 5, the part after the 10th digit is omitted.

For example: Rounded to the nearest ten.

Rounded to the nearest ten.

3. Rounding to the hundred digit means that a number is accurate to the hundred, and the part after the hundred digit is omitted. When the value of the 10 digit is greater than or equal to 5, the value of the 100 digit is increased to 1, and then the part after the 100th digit is omitted. When the value of the 10 digits is less than 5, the part after the 100 digits is omitted.

For example: Rounding to the hundredth place.

Rounded to the nearest hundred.

4. Rounding to the thousand digits means that a number is accurate to the thousands, omitting the part after the thousands. When the value of the hundred digit is greater than or equal to 5, the value of the thousand digit is increased to 1, and the part after the thousand digit is omitted. When the value of the 100 digit is less than 5, the part after the 1000 digit is omitted.

For example: rounding to the thousandth place.

Rounded to the nearest thousand.

5. Rounding to 10,000 means that a number is accurate to 10,000 and the part after 10,000 is omitted. When the value of the thousand digit is greater than or equal to 5, the value of the 10,000 digit is added to 1, and then the part after the 10,000 digit is omitted. When the value of the thousand digits is less than 5, the part after the 10,000 digits is omitted.

For example: rounding to 10,000 digits.

Rounded to the nearest 10,000 digits.

What does "rounding" mean?

That is, the number after your decimal point is less than 5 and the number greater than five is rounded up.

What does "rounding" mean?

That is to say, if you round off four, five is about equal to ten, so you don't understand, for example, let's say, for example, 15, the mantissa is five, it is approximately equal, and the mantissa is 4, which is about equal to 10

What does rounding mean.

4 and the following are gone, and 5 and the latter are in one.

What does "rounding" mean?

Rounding: When taking the decimal approximation, if the highest digit of the mantissa is 4 or smaller than 4, remove the mantissa number. If the highest digit of the mantissa is 5 or the filial warrior is greater than 5, round off the mantissa and advance it to the previous digit"1", this method of approximating numbers is called rounding.

Mathematics, what does rounding mean, how to understand skillful grinding.

Not rounded to 4, more than 5 into one. It's like rounding up to 3, rounding one to 4 means?

Those below five are zeroed, and those above five are added to one.

Paraphrase. Round the digits after the decimal point of the mill, i.e., if the first digit of the rounded part is less than five, it will be rounded; If it is greater than or equal to five, the last digit of the reserved part is added to 1.

1. Rounding definition: a commonly used approximate calculation method. According to the need, the calculated number of prosthetic limbs are reserved to a certain digit, and the remaining part, when the first digit is not greater than 4, it is rounded off, and when it is not less than 5, it is rounded to the previous digit and advanced to 1.

When rounding off the whole number, a few zeros are added to the rounding of several integers.

2. As the name suggests, it is to use the method of discarding less than 5 and entering 1 with 5 in the valuation of numbers. For example, it is about 10, and it is about 9, which is the method of letting five into the four-grasp manuscript after the decimal point.

In fact, erasing a zero means erasing the zero。For example, if you buy a dress for 292 yuan, and the boss says that you will make a shed, you will erase the 2 yuan discount, which means that it will be sold to you for 290 yuan. Erasing zero is generally to erase the fraction of the mantissa number, not to directly remove 0 from the amount of money.

However, some black-hearted merchants will use the "rounding" method of erasing zero. There have been consumers who found that they only consumed 101 yuan when they were eating, but they were charged 101 yuan when they paid. The restaurant cashier's response to this was: the computer system rounds by default and cannot refund the money.

In fact, if this is the billing method, consumers should be informed in advance that rounding up is a voluntary act of the merchant, while "five fiber ridges" should require the consent of consumers and cannot be compulsory.

If the merchant does not take the initiative to explain to the consumer that the fraction will be "rounded" at the checkout before consumption, and allows the consumer to choose whether to destroy the consumption, it is not clearly marked with the price, and this behavior is a violation of the consumer's right to know

Rounding"It is a mathematical method that approximates the magnitude of a numerical value. It is used to adjust a numeric value according to a certain rule to become closer to a certain precision or a number of digits.

Specifically, the rules for rounding are: when the number to be adjusted is less than 5, it is rounded down (i.e., discarded), and when the number to be adjusted is greater than or equal to 5, it is rounded up (i.e., one unit is added). This allows the raw number to be adjusted to the nearest integer or to a decimal for a specified number of digits.

For example, if you round to an integer, the result is 3.

Rounding to an integer place, the result is 7.

Rounding to two decimal places, the result is .

Rounding is often used in everyday life and in various areas of computing, and it can simplify the digital process and bring the results closer to reality.

Rounding"is a method of mathematical calculation used to approximate a decimal or fraction to an integer or a numeric value of a specific precision. Its rules are:

If the decimal part is less than 5, it is rounded.

If the decimal part is greater than or equal to 5, it will be carried and the integer part of the previous call will be added by 1.

For example, if you want to approximate the decimal to one decimal place, apply the rounding rule, and the result will be. If yes, approximate to one decimal place, the result will be.

Rounding"This expression is also often used to describe the method taken to make decisions or deal with problems according to certain rules of approximation or rounding, usually for convenience or simplification.

Rounding is also simplification, which is equivalent to not having the decimal point behind it to be a whole.

"Rounding" means that the spine rounds the digits after the decimal point, i.e., if the first digit of the rounded part is less than five, it is rounded; If it is greater than or equal to five, the last digit of the reserved part of the key servant is added to 1.

Pronunciation: [ sì shě wǔ rù ].

Sentence formation: 1If the number is equal to or higher than 5, it is rounded to the nearest ten digit.
