How can I round fractions to a specific number of digits? I want a calculation on a character sheet that shows the result with 2 digits. So for example, if my calculation gives a result of 12.58946, I would like it to round that to 12.59 in the displayed number. Is there any way to do this?

Its not pretty, but something like this might work: ((( formula )*100)d1/100) but the nature of floating point math is that you might hit a case where it still has more digits. Someone else might have a better idea... (Brian?)

Using floor((formula) * 100) / 100 may produce nicer results than using d1s. ETA: This would produce 12.58 rather than 12.59. You can substitute round for floor to round the last digit(s) if necessary.

Thank you very much! Worked like a charm! Now I can choose how many digits to display!
