Random Function

Returns a random number within the specified range. If the iRange variable is empty, the function generates a float random number within the range from 0 to 1. If the parameter is specified, the function generates a random integer in the range 0..iRange - 1.

Parameters

A randomly generated value whose type depends on the function implementation:
If iRange is not specified, the return value is a float-type random number. If iRange is specified, the function returns an integer number.

To initialize the random number generator, add a single call to Randomize (see Randomize) or assign a value to the RandSeed variable before making any calls to Random. The RandSeed variable holds the initial value for the random number generator. It allows you to generate the same sequences of random numbers.
