The RANDARRAY function returns an array of random numbers. Users can specify the number of rows and columns to fill, minimum and maximum values, and whether to return whole numbers or decimal values. For example:
Argument
Required
Description
[rows]
N
The number of rows to be returned
[columns]
N
The number of columns to be returned
[min]
N
The minimum number you would like returned
[max]
N
The maximum number you would like returned
[whole_number]
N
Return a whole number or a decimal value: true for a whole number, false for a decimal number.
Note:
The RANDARRAY function is only valid when allowDynamicArray is true.
The RANDARRAY function will return an array, which will spill if it's the final result of a formula.
If you don't input a row or column argument, RANDARRAY will return a single value between 0 and 1.
If you don't input a minimum or maximum value argument, RANDARRAY will default to 0 and 1 respectively.
The minimum number argument must be less than the maximum number, otherwise RANDARRAY will return a #VALUE! error.
If you don't input a whole_number argument, RANDARRY will default to FALSE, or decimal value.
