Re^2: sprintf and decimals

in reply to Re: sprintf and decimals
in thread sprintf and decimals

thanks. So that'll be why this bit of code returns the following

#!/usr/bin/perl

$w=2.315;
$x=2.3150141;
$y=sprintf("%.2f", $w);
$z=sprintf("%.2f", $x);

print "$w rounded is $y\n";
print "$x rounded is $z\n";

2.315 rounded is 2.31
2.3150141 rounded is 2.32

oh! I didn't know it looks at more than the next digit. To continue the example in my previous post, that means 5.1 > 5, so 2.6751 rounds to 2.68	[reply]
