Which variables should I typecast when doing math operations in C/C++?

Question

For example, when I\'m dividing two ints and want a float returned, I superstitiously write something like this:

int a = 2, b = 3;
float c = (float)a / (floa         


        

Answer 1

I think as long as you are casting just one of the two variables the compiler will behave properly (At least on the compilers that I know).

So all of:

float c = (float)a / b;

float c = a / (float)b;

float c = (float)a / (float)b;

will have the same result.
