Re: unsigning NSNumber

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). hth, Graham On 23 Jul 200

unsigning NSNumber

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 ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to
