ns_rand
ns_rand(3aolserver) AOLserver Built-In Commands ns_rand(3aolserver)
__________________________________________________________________________________________________________________________________________________
NAME
ns_rand - commands
SYNOPSIS
ns_rand ?max?
_________________________________________________________________
DESCRIPTION
ns_rand generates a cryptographically-secure random number. If max is not specified, the random number is a floating-point value n such
that 0.0 <= n < 1.0.
If max is specified, it must be a positive integer between 0 and 2147483647. The return value is an integer value such that 0 <= n <= (max
- 1).
Internally ns_rand is implemented with the drand48(3) and lrand48(3) standard library functions. An internal random seed is generated the
first time ns_rand is called after the server starts.
EXAMPLES
nscp> ns_rand
0.39938485692
nscp> ns_rand 10
