`rand` also supports something like that. I asked about numbers between 0 and 1. But thanks. `$_="msh210";$"=$\;@_=@{[split//,uc]}[2,0];$_="@_$\1";$\=$/;++$_[0]for$...1;print lc substr crypt($_,"@_"),1,6`	[reply] [d/l] [select]

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;` [download] Regards, Mario. Edit: Applied correction. Thanks pryrt.	[reply] [d/l]

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.	[reply] [d/l] [select]

Math::Random::Secure's irand function supports integer between x and y inclusive. Ah yes, that will not work for 0 and 1.	[reply]
