FilterFactory - Function "rnd"

Back to function listing

Random number between a and b, inclusive
Note: Modifies internal state

Syntax

rnd(a,b)

To change the seed, use rst(i)

rnd(0,255) does not initialize itself to e.g. some image properties or the clock.
The random values are always:
seed=0: 10, 35, 106, 115, 158, 111, 120, 91, 134, ...
seed=1: 148, 64, 179, 0, 248, 199, 35, 163, 176, ...
...

Implementation in Windows plugin 3.00a (beta version) and 3.00b (internal build)

In version 3.00a (beta version) and version 3.00b (internal build), if b<a, the result was not 0. Fixed the final version of 3.00.

Version 3.00a (beta version) and 3.00b (internal build) Version 3.00 (final) and 3.0.4
