Hello Mr. Muskrat and thanks for your reply,

> Perl's int is not the same as C's floor()..

I already admitted my superb ignorance but i read here that in C floor turns 1.6 1.2 2.8 2.3 into 1 1 2 2 or simply 'This function returns the largest integral value not greater than x'.

This is identical to the int function where any decimal are stripped out: say int $_ for qw(1.6 1.2 2.8 2.3)

> Perl has a pre-decrement just like C..

I have meditated a bit over this before trying to port the code and, sincerely I didnt read the C documents about post and pre increment, but as I have always understood the third part of the Perl's C style for loop is a statement on it's own: ie ++$var; or $var++; are identical.

Infact for($i=0;$i<4;$i++){say $i} and for($i=0;$i<4;++$i){say $i} produce the very same, expectable results. Switching between them in the above code does not change the result.
