Frage
What's different between:
CGFloat gray[4] = {0.9f, 0.9f, 0.9f, 1.0f};
and
CGFloat gray[4] = {0.9, 0.9, 0.9, 1.0};
?
I think they are the same but I don't know for sure.
Lösung
I believe it is indicating that the number is a float (i.e. single-precision floating point) as opposed to a double (double-precision floating point),
