rounding numbers

(OP)
how can you round a number up? so if the numbers 8.09181 it will round up to 9?

RE: rounding numbers

one guess.....


#!/usr/local/bin/perl

$num = '8.0134';
if ($num - int($num)) { $num = int(++$num); }
print "$num\n";


'hope this helps.

RE: rounding numbers

you could use sprintf() or POSIX::ceil

or you could do int($num+1)

RE: rounding numbers

thanks for your help, i used a different technique. i added 0.9999999 to the number and then cut the decimals off.

RE: rounding numbers

That is exactly what I said above:

int($num+1)
