I would have sworn there were optional parms to address the rounding. I was wrong.

Or just use SQL ROUND.

Using SQL is definitely sensible advice. The ROUND function in particular only does half-up rounding, though. To get some of the other methods, you would need to set the rounding mode and use QUANTIZE. I am actually not quite clear on how to set the rounding mode; it might not be easy (or even possible?) to switch modes in the middle of a program.

In that case, having a procedure or procedures to handle different rounding methods could conceivably be handy. (As a practical matter, I realize it is extremely unusual to need to dynamically switch rounding
methods.)
