= conditional operator?

There's an "Int Equals" component in the Compare component group. Or what do you mean?

a kind of (a>=0) & (a<=0) will work?

or is the & operator only reserved for 'mask' evaluation.. i mean can i use it as a kind of 'normal' AND ?

thanx

Hi lalo,

I think you meant something like:

(a>=b) & (a<=b)

it should work but be carefull comparing floats for equality, often float number that you'd consider equal have slightly different representations.

Yes indeed. You have to compare floats like "if Abs(a - b) < SomeEqualityThresholdValue then do something".

How's Abs with Synthmaker, btw? (and I don't mean the abdominal muscles)

ok, after talking with lalo, here's an update.

Lalo wants to compare a value with zero, the best way is to use a range. Also lalo wants it to be 1 when false and zero when true, something like:

1 - ( ( val > -.00001 ) & ( val < 0.00001 ) ) & 1;
