The standard Perl approach to rounding numbers (with sprintf) amounts to using a string manipulation for what is arguably an arithmetic task. Did you have any particular error in mind?

When I first saw the question, the two solutions I thought of were $x - int( $x ) or indeed something along the lines of $x =~ s/\d+(?=\.)//, and I'm curious about what errors could have resulted from the latter approach.
