in thread Determine steps between two numbers

IMHO in such case the variable name should be changed from 'increment' to 'decrement'. Or better - change algorithm to more intuitive: 
my $increment = ($second - $first) / ($steps - 1);
...
push @array, $first += $increment;

And one-line @array generator as alternative:

my @array = map { $first + $increment * $_ } 0 .. $steps - 1;

    Thanks. I transferred this over from my Java implementation of it and didn't quite get it right, so I did some stuff to make it work. You helped me get it back to what it was originally. Not too confident in the one-line generator you have there, but it'd be a nice touch anyway.

      Why? Don't you trust mathematics?

        I trust the math of it. It's not that I'm not confident that grizzley's solution is mathematically sound. Rather, I'm not confident in my own ability to fully understand that use of map, especially if I were to stop thinking about this and come back to it later. I also don't really see the need.
