integer(3) Perl Programmers Reference Guide integer(3) NAME integer - Perl pragma to compute arithmetic in integer instead of double SYNOPSIS use integer; $x = 10/3; # $x is now 3, not 3.33333333333333333 DESCRIPTION This tells the compiler to use integer operations from here to the end of the enclosing BLOCK. On many machines, this doesn't matter a great deal for most computations, but on those without floating point hardware, it can make a big difference. Note that this affects the operations, not the numbers. If you run this code use integer; $x = 1.5; $y = $x + 1; $z = -1.5; you'll be left with $x == 1.5, $y == 2 and $z == -1. The $z case happens because unary - counts as an operation. See the section onPragmatic Modulesin theperlmodmanpage. 3rd Berkeley Distribution perl 5.005, patch 02 integer(3)
