Name
rand -- generate a uniform random value between 0 and 1
Purpose
Returns a uniformly-distributed random number between 0 and 1,
using as a seed either the argument provided or, if none, the
Unix process number
Usage
rand [seed]
Arguments
seed = seed value for random number generator
Example
1) Return a random value:
punaluu{lris}165: rand
0.791128
punaluu{lris}162: ./rand
0.228747
Note that the values differ because the process number (used
by default as the random generator's seed) changed.
2) Return a random value for a given seed:
punaluu{lris}167: ./rand 12345
0.505545
punaluu{lris}168: ./rand 12345
0.505545
Note that the values are the same when the same seed is used.
