How to round CGFloat

Question

I made this method

+ (CGFloat) round: (CGFloat)f {
    int a = f;
    CGFloat b = a;
    return b;
}

It works as expected but it only round

For working with 32 and 64 bit you can create your own macro's like

#ifndef CGFLOAT_CEIL
    #ifdef CGFLOAT_IS_DOUBLE
        #define CGFLOAT_CEIL(value) ceil(value)
    #else
        #define CGFLOAT_CEIL(value) ceilf(value)
    #endif
#endif

Ps this isn't an answer for the question but an addition for the question about how to work with 32/64 bit values.

Define this in a file like MyMacros.h and than add an import in the myapp-Prefix.pch

Also remember that choosing CGFloat as prefix for your function can be a risk since apple might add a macro like this them self so that is why the #ifndef CGFLOAT_CEIL is
