Answer 1

line 113: int c2;
d2 is a double.

I am not sure what your code does so I can not tell which version is better.
a) double c2;
b) c2 = (int)(d2 * 1000) / 1000;

Answer 2

Btw: You should be familiar with double precision. I never used modulus operator with doubles. But I think it causes rounding problems.
