srandom

 

 

Description

The srandom function returns a pseudo-random number between zero and num.

When to use

The srandom function is used to produce a pseudo random number between zero and a specified number.

 

Syntax

(srandom num )

Name Description AIS Types
num The top of the range of the pseudo random numbers to be generated.Number

Returns:

Returns a pseudo random number between zero and num.

 

Examples

Here are a number of links to Lambda coding examples which contain this instruction in various use cases.

Example_Number_srandom_001

This example shows how the srandom function returns a pseudo-random number limited by the user-specified Number argument.
