This discussion centers around the results of a divide operation and rounding numbers that are x.50 exactly.
I was able to find out by trial-and-error that the Round() function in the Solidworks Equation dialog uses the common statistical rounding rules : If the number is even (4.50, 6.50, etc), it will round down whereas if it is an odd integer, it will round up (15.5 -> 16).
I am writing an equation and I need it to always have it round up if it is x.50. Is there another function that will do this? I have tried just regular dividing, which will always round down to the nearest INT and I have tried INT() which doesn't seem to work either.
Here are some real examples from my equations, their actual results, and what they calculate to with the different functions I have tried so far.
Ex1 (Odd-numbered Example)
( 1.5 * 15 + 1 - 0.25 ) / 1.5 = ??
Actual Result : 15.5
INT(( 1.5 * 15 + 1 - 0.25 ) / 1.5) = 15
Round(( 1.5 * 15 + 1 - 0.25 ) / 1.5) =16
Ex2 (Even-numbered Example)
( 1 * 12 + 1 - 0.25 ) / 1.5 = ??
Actual Result : 8.5
INT(( 1 * 12 + 1 - 0.25 ) / 1.5) = 8
Round(( 1 * 12 + 1 - 0.25 ) / 1.5) = 8
