push_rand

Declaration: void push_rand (EStackIndex num_idx )
Category(ies): Math
Description: Pushes a random number onto the estack. If num_idx indexes the
END_TAG then a floating-point number between zero and one is
generated. If the number indexed by num_idx is a positive integer then a
number between one and that number is generated. If the number indexed
by num_idx is a negative integer then a number between that integer and
minus one is generated.
num_idx — Indexes the input number (may index an END_TAG).
Inputs:
Outputs: None
Assumptions: None
Side Effects: May expand expression stack, cause heap compression, or throw an error.
Availability: On AMS 1.05 and higher.

Example: This example pushes a list of ten random numbers in the range [0.0, 1.0]
on the estack.
EStackIndex esi;
short i;
push_quantum( END_TAG );
esi = top_estack;
for (i = 1; i <= 10; i++)
push_rand( esi );
push_quantum( LIST_TAG );
