Thanks for the information guys.

Methyl - dividing by 1 also results in the answer being given to 3 decimal places with my version of bc.

Am I correct in thinking that for portability people just have to assume that bc's scale (to reduce precision) does not actually work, so if a result needs to be given at a certain (reduced) precision they have to use a printf modifier or such like?

Jim - when you say bc is "POSIX" does that mean there is a list of programs that are guaranteed to be on POSIX compliant OSs? If so where would I find the list? I just did a search and couldn't find anything. Or are the "" around POSIX meant to say - strictly unofficial? Is there an unofficial list?

Cheers.
