You can achieve what you want by generating a random number on [-1, 1]
and multiplying it by the max float.  I don't think that there is a
*general* way to arrive at a uniform distribution of a range greater
than max float by first generating a random number on [0, 1), so it's
unlikely that the library can be "fixed" to achieve what you want.
It's really quite easy.
if ( max - min == infinity )
{
    divisor = 2;
    min /= divisor;
    max /= divisor;
} else {
    divisor = 1;
}
Ah, I see.  Nice :)  Thanks for suggesting another simple solution.
