A fast method to round a double to a 32-bit int explained
...ll common, using type punning to get an integer out of a double was a huge win (see the benchmarks here, copied from a comment to the OP.) Your version is, of course, simpler.

What is the difference between NULL, '\0' and 0?
...implicitly checks "is not 0", so we reverse that to mean "is 0".
The following are INVALID ways to check for a null pointer:
int mynull = 0;
