Hi folks, Can anyone tell me the most efficient way to unsign a floatvalue in an NSNumber?
Like change a -1.47 to 1.47 ?
Thanks

//	Below reverses the sign of, in this case, a float
	float y, x; y = x = -12.0;
	y -= x * 2; // reverses the sign of x.
	printf("y = %f\n", y); // y = 12.000000

I don't think there's a method on NSNumber which does it for you, so obviously you'd need to extract the value from your NSNumber instance and then use the new value in a new NSNumber.

HTH,
