in thread inclusive rand

Unfortunately, Math::Random::Secure's dependencies have many sub-dependencies.

use strict;
use warnings;

use Math::Random::Secure 'irand';

# Random number between 0 and 1 inclusive (total 524288-1 numbers).

sub custom_rand {
    irand(524288) / 524287;
}

printf("%f\n", custom_rand()) for 1 .. 20;

    Since irand($n) returns [0,$n) => [0,$n-1] -- ie, not including $n -- you would have to divide by 524287 to get [0,1] inclusive.
