Strange behavior when casting an int to float in C

Question

I have a doubt concerning the output of the following C program. I tried to compile it using both Visual C++ 6.0 and MinGW32 (gcc 3.4.2).

#include 

        

Answer 1

On the first printf, the conversion from integer to float is done by the compiler. On the second one, it is done by the C runtime library. There is no particular reason why they should produce answers identical at the limits of their precision.
