# 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 that it's okay 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.
