Rats. I came up with this but didn't get it posted quickly enough to beat Jon:
::routine ceil return arg(1) % 1 + 1 - (arg(1) < 0) ::routine floor return arg(1) % 1 - (arg(1) < 0) which requires fewer function invocations (none if the value is in a variable) yet still demonstrates the elegance of Rexx operator evaluation. -Chip- On 3/14/12 06:57 Sahananda (Jon) Wolfers said: > I was afraid that might be the case.
