Why would they be unsafe? (They aren't.)
It's possible that using the double versions (the ones without the "f" suffix)
is inefficient in 32-bit mod

Yes, sorry - i meant /usr/include/math.h
Because CGFloat is typedef'd to float on 32bit and double on 64bit i
have to swap between, eg, atan and atanf depending on my build
settings. I have a framework which is intended to support 32bit and
64bit.

You should, I believe, be able to include ('type generic math' - a
C99 addition) instead, and then just 'use' the non-suffixed versions of the
functions. Hidden macro magic is supposed to then make the compiler call the
double or float versions as appropriate for the type used.

Just use atan(). 32-bit floats
But then e.g. when building 32-bit i still have to cast the return
value or i get the warning:-
'implicit conversion shortens 64-bit value into a 32-bit value'

Only on 32-bit. On the 64-bit runtime, CGFloat is a double, not a float, and
therein lies the problem. If
