Am I overlooking a simple method? Yes, a subroutine call is an expression, so it can be used as an argument to another subroutine. There are several ways to round a number, the easiest (especially if you don't care how it is rounded) is to use sprintf or printf: perl -e 'printf "%.2f\n", 100.12345' You can find out more about the formating specifiers in perldoc -f sprintf -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] http://learn.perl.org/
