(712/(712*30/100)/2+10)*10) Is NOT the same as ((30/100)/2+10)*10 Agreed. But it is the same as ((100/30)/2+10)*10. Your expression can be simplified: ($ImageSize/($ImageSize*$Percent/100)/2+10)*10 = 500 / $Percent + 100 For example: (712/(712*30/100)/2+10)*10 = 116.6667 500 / 30 + 100 = 116.6667 ...

Your expression is strange. It contains ImageSize twice, and they cancel each other. So the result does not depend on ImageSize. At the time writen the code, it was more important to understand what is going on thant make the code pretty. In this cas eI clearly can see that I A.. take the size of ...

Oh thank you sir.

That was exactly what I needed.
