Re^2: Improve my Code: Subroutines

my $r = ($i)*(1e-6); #radii are in microns

Why do you put both factors in brackets?

Integers will be presented without any loss of precision in Perl

But only as long as the number "fits" into perls integer type, which typically is a 32 bit signed integer or 64 bit signed integer. Once you exceed the limit (+/- 2³¹ resp. +/- 2⁶³), perl silently converts the value to a floating point number with loss of precision (perlnumber).

Why do you put both factors in brackets? I just copied it from the OP. There is no harm to using brackets here, they are just superfluous.
