Agreed. >That's why I think the two best solutions to this problem are: >1. Cast double constants to CGFloat >2. Write all constants as doubles, and build your 32-bit code with the >-fsingle-precision-constant flag > >(2) is my favorite since it's easier and less messy. I guess (1) is best really, but it's so ugly and annoying. >> Similarly, there >> is no CGFloat version of sin() and other math functions. > >Yeah, I solved that one by using macros, like this: (typed in Mail but >should work) > >#if CGFLOAT_IS_DOUBLE == 1 >#define MyCGFloatSin(x) sin(x) >#else >#define MyCGFloatSin(x) sinf(x) >#endif I'm looking forward to going 64 bit-only, but waiting for the tools to catch up. :) I know you are too. :) -- ____________________________________________________________ Sean McBride, B.
