MOD() function return the remainder after number is divided by divisor in excel. the result has the same sign as divisor.
But there are some differences in C#. For specific practices, you can refer to this formula.
quotient = floor(dividend / divisor)
mod = dividend - (divisor * quotient)
double a = -1.779406909;
double b = 2 * Math.PI;
double d = a - (b*c);
