Is there any accuracy lost when dividing a CGFloat by a NSTimeInterval?
I am trying to translate a NSTimeInterval to a UIView.frame.size.width and currently casting it to a float.

An
NSTimeIntervalis a typedef for adouble, which is guaranteed to have at least as much precision as aCGFloat(CGFloatis defined as afloaton 32-bit systems and adoubleon 64-bit systems).So no, diving a
CGFloatby anNSTimeIntervalwill not lose any accuracy (compared to dividing it by anotherCGFloatthat is; floating-point math always has precision/accuracy worries).
