float val = [mySignedNumber floatValue];
NSNumber* myAbsoluteNumber = [NSNumber numberWithFloat:fabsf( val )];
(note NSNumber is immutable so you can't change what it contains to
remove the sign. You can create a new NSNumber with the absolute value
however).

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
