explicit cast building own math library

Hello,
I'd like build my own math class library (without using cmath or other). I'm doing the division:
At the moment I'm doing operation between integer and every method ust return an integer; IDiv return the integer part if it cannot do the division; to do this I thought to exploit (int); see below:

Code:

---

int IDiv( int a, int b ) { 
    assert (b != 0);
    return (int) ((float) a / (float) b);
}

---

Is it beautiful?
Willing avoid the C/C++ math library, now I'm wonder how to do the rest of a division.....
Suggests?

First question: why do you want to avoid the C-math library? There is nothing wrong with it.

Second question: are you are looking for floating point math routines for non-FP CPUs? If yes, have a look at http://www.radiks.net/~rhuebner/mathlib.html.

Comment on the current code: do not use C-style casts.

to do exercise. If used math.h, what does remain to do?

And If I used a C compiler?

Why do you ask rhetorical questions?
