RANDBETWEEN function

PRO BASIC

The RANDBETWEEN function in Jspreadsheet Formulas Pro is used to generate a random integer between two given numbers, both numbers included. The generated number will change every time the worksheet is recalculated. This function is handy when you need a random number within a specific range for your calculations.

Documentation

Generates a random integer between two specified numbers (inclusive). The value of the number changes each time the worksheet is calculated or when the function is recalculated by pressing F9.

Syntax

RANDBETWEEN(bottom, top)

Parameter	Description
`bottom`	The smallest integer in the range of acceptable values.
`top`	The largest integer in the range of acceptable values.

Behavior

The RANDBETWEEN function generates a random integer between the two numbers you specify. The function takes two arguments: the bottom and top of the range in which to generate the random number. Here's how it behaves:

If the bottom is greater than the top, the function returns an error.
If either the bottom or top is a non-integer, the function rounds it to an integer.
If either the bottom or top is a boolean, it is converted into an integer before the function is evaluated (TRUE becomes 1, FALSE becomes 0).
If either the bottom or top is a text string or an error, the function returns an error.
Empty cells are treated as zero.
Each time a worksheet using the function is recalculated by a new or edited entry, a new random number is generated.

Common Errors

Error	Description
#NUM!	Occurs when the bottom is greater than the top
#VALUE!	Occurs when either argument is a text string or an error

Best practices

Avoid using RANDBETWEEN function where stable and unchanging values are required. Since the function generates a new random number each time the worksheet is recalculated, it may lead to unexpected results.

Remember that RANDBETWEEN function includes both the bottom and top values in the range. If you don't want to include one or both of these values, adjust your input accordingly.

Use the RANDBETWEEN function with the SORT function if you want to generate a set of unique random numbers.

Be careful when using RANDBETWEEN in large ranges or in many cells. It may slow down the worksheet's performance.

Usage

A few examples using the RANDBETWEEN function.

RANDBETWEEN(1,10)  
→ Returns a random integer between 1 and 10 (inclusive).

RANDBETWEEN(-5,5)  
→ Returns a random integer between -5 and 5.

RANDBETWEEN(100,200)  
→ Returns a random integer between 100 and 200.

IF(RANDBETWEEN(1,6)<=3, "Heads", "Tails")  
→ Simulates a fair coin toss.

RANDBETWEEN(1,6)  
→ Simulates rolling a six-sided dice.
