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
        7
