in reply to Big ints and random ints

Generate the random number by sticking together N random digits to get. For example, if you want a random number between 1e30 and 9.99e39:

my $num = join '', map { int rand 10 } (0..(30 + int rand 10) );
Update actually, you don't even need the rand at the end; to go from 0 to 9.99e39:
my $num = join '', map { int rand 10 } (0..39);
as numbers of 38 digits or less will have zeroes prepended to them.
