NAME ^

Math::LogRand - Perl extension to return a random number with log weighting.

SYNOPSIS ^

        use Math::LogRand;
        my %test;
        my $min = 20;
        my $max = 100;
        $test{ LogRand($min,$max) }++ for 0..1000;
        print "$_\toccured $test{$_} times.\n" foreach sort keys %test;

DESCRIPTION ^

This module attempts to implement a scalar version of the MATLAB logrand function.

Accepts two arguments: the floor of distribution, and the ceilling of distribution.

Returns a 'random' integer produced by the Perl rand() function, between input parameters, with weighting to low integers by log distribution.

How good/bad this is, I don't know: it's really for my own convenience, but I hope you find it useful. Any suggestions really very gratefully received!
