Mathematical Functions: Random Functions

rnd, birnd

          rnd(x)     (init- or control-rate only)
          birnd(x)   (init- or control-rate only)

Description

Where the argument within the parentheses may be an expression. These value converters sample a global random sequence, but do not reference seed. The result can be a term in a further expression.

Performance

rnd(x) – returns a random number in the unipolar range 0 to x.

birnd(x) – returns a random number in the bipolar range -x to x. rnd and birnd obtain values from a global pseudo-random number generator, then scale them into the requested range. The single global generator will thus distribute its sequence to these units throughout the performance, in whatever order the requests arrive.
