USE EXCEL S VBA TO FIND RANDOM NUMBERS

Here's a look: excel toolset 00130 generates random numbers (random time, random integers, random values, unique random values).

1. The formula of the random function is: rand(), if you need to specify the number of decimal places behind the generated data, you can enter the formula: =round(rand(),1).

2. Click Enter, and you can see that the generated data retains 1 decimal place.

3. If you need to generate random numbers with a value between 1 and 3 and keep 1 decimal place, you can use the formula: =round(rand()*3-1)+1,1).

4. Click Enter to generate a random number between 1 and 3 with 1 decimal place.

1. First of all, double-click the excel sheet on the computer desktop with the left mouse button to start the excel sheet.

<>3. Enter the formula "=randbetween(5,10)" into the cell, and then click the enter key on the keyboard.

4. As you can see, the target cell at work automatically generates a number of 5 10.

<>7. Press F9 on the keyboard to refresh and regenerate other numbers that meet the requirements.

1. The formula of the random function is: rand(), if you need to specify the number of decimal places behind the generated data, you can enter the formula: =round(rand(),1).

2. Click Enter, and you can see that the generated data retains 1 decimal place.

3. If you need to generate random numbers with a value between 1 and 3 and keep 1 decimal place, you can use the formula: =round(rand()*3-1)+1,1).

4. Click Enter to generate a random number between 1 and 3 with 1 decimal place.

1. First open a blank excel document, there is nothing in the document:

2. Then enter the formula in any cell, the round function here is to keep the decimal point, the first parameter is the data source, the second is the number of digits to be reserved; The rand function is to obtain random numbers, and the following "*(3-1)+1" is to limit the range of numbers, 3 is the maximum number, 1 is the minimum number, and it is a fixed formulation. When you're done, pressing enter generates a random number:

3. Then select the cell of the random number, and put the mouse up and down to get a series of random numbers. The above is the usage of excel to generate random numbers:

1. First of all, open the excel office software, the version used in this demonstration is the home and student version 2016, and other versions are also acceptable.

2. Create a new excel** and enter the demo data, and display the result cells with light blue shading, so that you can see the results more intuitively.

3. Move the mouse to the C6 cell and double-click to enter the formula, the formula content is "=round(1+(3-1)*rand(),2)", which means that the value is taken between 1 and 3, and the two digits after the decimal point are retained.

4. After the input is completed, press enter to see the current display result, the result is a random number, so the display is different each time.

5. Use the format fill handle on the C6 cell to select all the cells with light green shading below, and you can get some random numbers.

=round(1+rand()*2,1)

To get a random number between a b:

a+rand()*b-a)

round() to get the number of digits you requested!

Yes, it can be set. Set the decimal place of each space in **. The system will automatically round you up.

Take a random number between 10 and 30 and divide it by 10

int(rand()*20+10)/10

Just use the random number formula round:

round(minimum value + (maximum value - minimum value) * round(), the number of decimal places is preserved).

If you use this formula to solve the problem, it should be written as:

round(1+(3-1)*round(),1) to get a random number.

Taking the subject's question as an example, substituting the formula yields:

Use the randbetween function to produce a range of random values whole difference part, formula: =randbetween(min, max); Generate random numbers (decimal part) with rand function, formula=rand(); Use the round function to deal with the number of decimal places, and the formula is pronounced cheating skin = round (numeric value, keeping the number of significant places after the decimal point). Combine the three functions together.

Suppose a random number between 5 and 10 is generated, keeping the 3 significant digits after the decimal point Buhu. The whole formula is: =round(randbetween(5,10)+rand(),3).

You can directly use the randbetween function to generate a random number orange hole within a certain range.

The rand function can be used in combination with other functions to generate random numbers within a range of circles.

randbetween [syntax].

randbetween（bottom,top）

bottom parameter: The smallest integer that randbetween will return.

Top Parameter: The largest integer that randbetween will return.

Example: randbetween(1,100).

A random integer (variable) greater than or equal to 1 and less than or equal to 100

randbetween(-1,1)

A random integer (variable) greater than or equal to -1 and less than or equal to 1

Note: The randbetween function will only generate random integers. If you need random decimals, you can use them in combination with the RAND function.

In Excel version 2003 or later, enter =rand() directly in the cell

Get a random number greater than or equal to 0 and less than 1.

Examples of other build methods:

Generate a random number between A and B (a random number is entered in the first cell: =rand()*b-a)+a

For example, if the tremor generates a random number between 1 and 10, input: =rand()*9+1

For the remaining numbers, place the mouse in the lower right corner of the grid, and when it becomes a cross, drag it down.

Generate a random integer between a and b (a random number is entered in the first cell: =int(rand()*b-a)+a).

For example, to generate a random integer between 1 and 10, enter: =int(rand()*9+1).

For the remaining numbers, place the mouse in the lower right corner of the grid, and when it becomes a cross, drag it down.

Generate a random number between A and B (A random number B).

In the first box, enter =rand()*b-a+1)+a

For example, to generate a random number from 1 to 100, enter: =rand()*100+1

1. First of all, enter the random function formula imitation family in the cell of excel**: =rand().

2. Click Enter to generate a random number, the size range of the data cannot be controlled, and it needs to be set within a certain range.

3. For example, if you need to set it between the number 5 and the number 15, you can input a random function: =rand()*15-5)+5.

4. Click Enter, you can generate the calculation result of the input formula, and you can see in the figure below that the generated random data is between 5 and 15.

The random number formula isrand functionis a random function in Excel that generates random numbers.

1. The rand() function is a random function that generates random numbers in Excel, and the random numbers returned are greater than or equal to 0 and less than 1 uniformly distributed.

Random real numbers, the rand() function will return a new random real number every time it calculates the worksheet.

2. The rand() function is a random function that generates random numbers, and there are also srand() functions in the C language, which are described in detail.

3. Because the rand() function generates integers in a specified order, the same two values are printed every time the above statement is executed, so the randomness of the C language is not really random, and sometimes it is called pseudo-random.

4. Function rand in the standard C library

A random number between 0 rand max can be generated, where rand max is an integer defined in , and it is system-dependent.

5. In order to generate a new sequence of random values each time the program is executed, we usually provide a new random seed for the random number generator. The function srand() (from which the seed can be sown for the random number generator.)

6. Wu Zena, as long as the seeds are different, the rand() function will produce different random number sequences, which is called the initializer of the random number generator.

The problem has changed again.

Take 90 out of 100 you said earlier.

There are 17310309456440 combinations in total.

** The t in is the time (in memory) for excel to perform 1000 calculations, and the seconds are calculated by running on my computer.

17310309456440 * 90 1000 * hours is also hours.

It's going to be almost a year.

If only the above array randomly shuffled the order.

With the following **.

sub fdsa()

dim arr(1 to 10, 1 to 10)dim i as byte

dim j as byte

for j = 0 to 9

for i = 0 to 9

arr(i + 1, j + 1) = j + i * 10next

nextfor i = 1 to 10

for j = 1 to 10

ii = int(rnd * 10 + 1)jj = int(rnd * 10 + 1)temp = arr(ii, jj)

arr(ii, jj) = arr(i, j)arr(i, j) = temp
