divide lesser number by greater
Jan 19th, 2010, 3:39pm  
I'm probably being an idiot here but in hacky old actionscript I can do..

var t : Number = 1/2;

which equals 0.5.

I can't seem to see an easy way of doing this in processing.  It rounds down to 0.

Sure there must be a way.

Cheers

Code:

// Results in 0.0
float f = 1/2;

//Results in 0.5
float f = 1.0/2;

In the first case Processingattempts to evaluate "1/2" it will consider this integer division (divide and discard fractional part) so the result will be an integer.

In the second evaluation of "1.0/2" is a mixed type calculation so Processiong will use the precision of the more 'accurate' type found in this case float, so performs a floating point division thus resulting in 0.5
