Abbreviation: R <SHIFT+N>
TYPE: Floating-Point Function
FORMAT: RND (<numeric>)
Action: RND creates a floating-point random from 0.0 to 1.0.
The computer generates a sequence of random numbers by performing
calculations on a starting number, which in computer jargon is
called a seed. The RND function is seeded on system power-up.
The <numeric> argument is a dummy, except for its sign (positive,
zero, or negative).
If the <numeric> argument is positive, the same "pseudorandom"
sequence of numbers is returned, starting from a given seed value.
Different number sequences will result from different seeds, but
any sequence is repeatable by starting from the same seed number.
Having a known sequence of "random" numbers is useful
in testing programs.
If you choose a <numeric> argument of zero, then RND generates
a number directly from a free-running hardware clock (the system
"jiffy clock"). Negative arguments cause the RND function
to be re-seeded with each function call.
