Overview
The Random function returns a random integer from 0 to 0x7FFF (32,767).
Syntax/Parameters
Syntax
int = Random ( );
Parameters
(none)
Return Value
Returns an int as a random value.
Remarks
The random number is generated by an algorithm that returns a sequence of apparently non-related numbers each time it is called. This algorithm uses a seed to generate the series, which should be initialized to some distinctive value using the SeedRandom function.
A typical way to generate trivial pseudo-random numbers in a determined range using the Random function is to use the modulo of the returned value by the range span and add the initial value of the range:
v1 = Random() % 100; // v1 in the range 0 to 99
v2 = Random() % 100 + 1; // v2 in the range 1 to 100
v3 = Random() % 30 + 1985; // v3 in the range 1985-2014
Notice though that this modulo operation does not generate uniformly distributed random numbers in the span (since in most cases this operation makes lower numbers slightly more likely).
