Is numerical application the same as numerical calculation?

In the same way, the textbook we use is called the calculation method, and the course arrangement is numerical analysis.

It's the same, I studied this subject, and our teacher said he had these two names.

If you think about it, you know that these two names mean the same thing.

Data analysis and data mining represent two different directions, data analysis tends to conduct first-class or confirmatory analysis of existing data, and the tools used are generally Excel, SPSS, etc.; Data mining prefers the use of algorithms to analyze existing data. As for numerical analysis, this is not very common in the field of data analysis and is a university course.

This is due to the fact that you don't use rounding correspondence in column k, and column l uses the function and sets the number of digits to be displayed is 2 digits, which is different, if you add the number of decimal places in column l, you can find the problem, as follows: The front is column K, and the back is column L, especially the two digits displayed in column K, and the actual participation in the calculation is 3 digits, do you want the result to be the same? The best thing to do in this case is in Tools --Options --Recalculate --Workbook Options, and tick "Based on display precision" so that they all have the same result.

And there is no need to set the function to take the bit, but directly set the cell format data to 2 decimal places, and there will be no problems in subsequent calculations. In addition, you have a few numbers The base of this column is different, such as the second person, the payment base and the pension insurance number are inconsistent, if you sum it may have problems, please check it.

1. Are the formulas and functions you use the same?

2. Whether the numbers you enter are in text format or numeric format, and whether they are the same (the numeric value will be on the right by default, and the text will be on the left by default).

3. Is there any unintentional space in the process of digital input?

4. Whether the entered number exists in the decimal place, and the number of decimal places is not displayed after setting.

5. The input number cannot be added with text, such as: 5 yuan, 10 catties and other units.

6. It is recommended to set the format of the cells where these numbers are located to the regular format, and then see if it is the same.

2. Whether the numbers you enter are in text format or numeric format, and whether they are the same (the numeric value will be on the right by default, and the text will be on the left by default).

3. Is there an unintentional space 4 in the process of digital input, whether the input number exists in the number after the decimal point, and the number of decimal places is not all displayed after setting.

5. The input numbers can not be added with text, such as: 5 yuan, 10 catties and other units 6, it is recommended to set the format of the cells where these numbers are located to the regular format, and then see if it is the same.

You still have something different, otherwise it can't be different. Just like 1+2=3Yes, as long as the units are the same, it will always be = 3, unless the units are different.

What's so strange about this is that some functions are inherently like this, such as input:

rand()；=rand()；=round(100*rand(),2)

randbetween(2,50)；=randbetween(3,10)

now()；=second(now())=hour(now())=today()

row()；=column()

And so on......These functions have the same formula, but the results are hardly the same.

Discrepancies in display: For example, the number of decimal places in cell formatting will be rounded when displayed, but the actual value will not change. Therefore, when using numbers in finance, sometimes the "based on the displayed value" in the "Options" section will be checked

Update method: If manual recalculation is set in the option, the data will not be automatically updated with the calculation accuracy: there is a certain limit to the numerical accuracy of Excel processing, and there may be differences if it is a very accurate data.

Iterative calculations: For some cyclic calculations, the larger the number of iterations, the more accurate it is.

The value calculated by the formula is different from the value calculated by the calculator, and you only need to set it in Excel.

Tools to prepare: excel software, computer.

1. Open Excel, and in the table, select the file in the upper left corner.

2. Select the option function in the file drop-down menu.

3. After clicking on the option, the excel option will pop up, and then select Advanced.

4. Find "When Calculate this Worksheet" in the advanced selection, and choose to set the precision to the displayed precision, that is, check the box on it.

5. After ticking, a prompt will pop up, click OK to complete.

Accounting software calculators excel formulas, all involve rounding, and your differences are due to the difference in the accuracy of the three.

If all the formulas are accurate to the score, the calculator and accounting software need to be set accordingly, and each formula involving a value in excel must be added to =round(*,2) If the original formula is =a1 b1, now it should be changed to =round(a1 b1,2).

Because ecxel keeps two decimal places after summing the sum, and you are taking two decimal places first and then calculating the error.

For the computer, taking two decimal places is only a formal reservation, and his actual value does not change.

If you want to do the same as your manual calculation, you can take 2 decimal places for the first two numbers, and then calculate =round(,2)+round(,2).

If you want to solve it, it depends on what kind of result you want, if you want it, don't move anything, you want, you can do it according to my formula, of course, the data can be replaced with variables, then enter it in C1.

round(a1,2)+round(b1,2) enter a few sets of data in a1 and b1 to try to know.

Either the formula itself is wrong, or the data display format is wrong.

My excel result is indeed so definitely that you pressed the calculator when you pressed it wrong.

Set the number of decimal places on the calculator the same as the Excel decimal pull.

To add a list of ticket numbers first, you can use the formula to get it.

The above mockup is for reference. Note that the formula in the figure is =large(($a$2:$a$10=e2)*$c$2:

c$10,countif($a$2:$a$10,e2))/max(($a$2:$a$10=e2)*$b$2:

b$10), press Ctrl+Shift+Enter to end when the input is complete, which is the array formula.

Final yield: e2=min(if(a$2:a$9 = a2,c$2:

c$9)) max(if(a$2:a$9=a2,b$2:b$9))*100, arrayized control+shift+enter

Please click Enter a description.

=sumif(a:a,"a",c:c)

The result is the sum of the bad numbers of ticket A.

Array formula: max(if(a:a="a",b:b,0)) The result is the maximum number of tickets to be put into the ticket.

And then ......You should know it!

Remember that the second formula is an array formula, and after pasting or typing, you must press the 3 keys Ctrl+Shift+Enter at the same time to finish, otherwise the formula will be invalid.

1.If the two ** formulas and columns are all the same, you have to use sheet1!a1=sheet2!A1 Drag and drop 2If the two tables need to match the conditions and then reference, it is recommended to use vlookup.

Enter or copy and paste the following formula in e2.

sumif(a:a,a2,c:c)/maxifs(b:b,a:a,a2)

or =if(countif(a$2:a2,a2)=1,sumif(a:a,a2,c:c) maxifs(b:b,a:a,a2),"")

Pull-down padding.
