int

See the current Perl documentation for int.

Here is our local, out-dated (pre-5.6) version:


int - get the integer portion of a number



int EXPR

int



Returns the integer portion of EXPR. If EXPR is omitted, uses $_. You should not use this for rounding, because it truncates towards 0, and because machine representations of floating point numbers can sometimes produce counterintuitive results. Usually sprintf() or printf(), or the POSIX::floor or POSIX::ceil functions, would serve you better.
