So what is the recommendation for 64-bit development? Do we really
have to litter our code with (CGFloat) casts all over the place, or
is there some way we can tell the compiler to treat our floating
point literals as float on 32-bit and double on 64-bit?
As I said earlier in this thread, the compiler flag -fsingle-precision-
constant tells GCC to treat double constants as if they were float
constants. Use it when building your 32-bit executables and you won't
lose any precision when doing math in your 64-bit executables.
