multiplication and division syntax
Oct 8th, 2006, 8:18pm  
perhaps this is old news, but i just had an issue with it.  i tried to do this simple algebra:
(8/3)*110=?

should be 293.333(repeating) using standard syntax.

processing is giving me the value
(8/3)*110=220

in order for it to compute properly i must enter
(8*110)/3=293.333

thought i would drop it in the board.

The problem is that unless you specify otherwise, Java assumes you're using integers for a reason, and so does an integer divide.
If you want to make sure that it doesn't throw the fractional part away, you need to make sure at least one of the parts of the divide is a floating point number, either by adding .0 to the end, or casting it to a float: (float)8 or float(8).
