RANGE in Empower formula
I have a custom field with the formula RANGE(ROUND(Amount,0),CConst1,CConst2) and my current spec states the range is 90-100 (integers) but if I put 90 in CConst1, it doesn't include this value because Range excludes the first value (X+1,Y). I tried to account for this by editing the formula to RANGE(ROUND(Amount,0),CConst1-1,CConst2) but strangely when I tested this formula it didn't work. I got an Amount value of 98.769 which when rounded to zero decimal places rounds to 99 so I put 100 into CConst1 and it should have included 99 because 100-1 is 99 but my value came to Fail instead of Pass. Am I missing something here about the formula or does Empower not work when you subtract 1 from CConst?
