Out of curiosity, what is the difference between what you posted and a int i = (int)f;?

@Montecristo : (int) f in Java is like static_cast<int>(f) in C++.

Ok... so I think I'll have to look for those two c++ methods to get the whole picture, thanks :)

@Montecristo : They are cast operators, not methods.

@Rahul G: Thanks for the correction, I do not know c++

Note the C++ version uses int reference. Thus modifying the float will cause the int to change (in some undefined way). The Java version does not provide that functionality. Every change to 'f' must be followed by a call to floatToIntBits().
