in reply to Misunderstanding with Math::BigInt

The first problem is that 2.87... & 0.002 are not ints, so BigInt doesn't help. You need Math::BigFloat. 

use Math::BigFloat;
my($out,$diver,$grade) = map{ 
    Math::BigFloat->new( $_ ) 
} split(/,/, ' 2.84894533078051,5,0.002', 3);

print $out ** ( 1/$grade ) * $diver;

    thanks a lot !!! it works perfectly.
    but is there a way to get only the whole number (without what after the dot) ? i tried int() but it rounds the whole number somewhy...

      Here's one way: 

      print +( split '\.', $out ** ( 1/$grade ) * $diver )[ 0 ];
