Subject: Unexpected results from the int() function
I am using ActiveState Perl and I am getting interesting results with I use
the int() function. Essentially, I get different results as in the
following. Is this normal for Perl?
I have narrowed my code to the following simple scenario:
my $a = 31.0;
my $b = 1.8;
my $c = 2.9;
my $sumy = $a + $b + $c; # $sumy = 35.7
my $yten = $sumy * 10;
my $ytenint = int($sumy*10);
print "x = " . $yten . " \n"; # output> 357
print "xint = " . $ytenint . " \n"; # output> 356
Try this
$ytenint = int(($sumy*10) . '.0'); # connect string '.0' to number
or this
$ytenint = int( '' . ($sumy*10)); # connect empty string and number
Both work as expected but for C programmers this is crazy :-)
