Re: strange rounding

Oh no, not that FAQ again.

Anyway, the best way to round to two decimals, is using sprintf:

$units = sprintf "%.2f", $units*$p;
[download]

In case you don't like trailing zeroes (maybe you do), as in "124.00", you can get rid of them using

$units =~ s/\.?0+$//;
[download]

turning "123.50" into "123.5", and "124.00" into "124".

Only do this when you know your number contains a decimal point.

I have found Math::Round a great package for rounding. `$perl -MMath::Round -e "print nearest(0.01, 3.14159)" 3.14` [download] *"Look, Shiny Things!"* is not a better business strategy than compatibility and reuse. OSUnderdog	[reply] [d/l]
