How does C compute sin() and other math functions?

http://stackoverflow.com/questions/2284860/how-does-c-compute-sin-and-other-math-functions

does C compute sin and other math functions I've been poring through .NET disassemblies.. can't seem to find anywhere the actual implementation of sin and other math functions... they always seem to be referencing.. and have written my own routines to compute functions using taylor series for fun. I'm curious about how real production..

a 3D sphere in Opengl using Visual C I am not able to create a simple 3D sphere using.. Visual C I am not able to create a simple 3D sphere using the OpenGL library function glutSolidSphere in C . Here's what.. However there's nothing special in and about it. And since it's tied to GLUT I'd not use it. Instead if you really need..

Why does modulus division (`%`) only work with integers?

http://stackoverflow.com/questions/6102948/why-does-modulus-division-only-work-with-integers

I recently ran into an issue that could easily be solved using modulus division but the input was a float Given a function.. the input was a float Given a function which repeats ex sin and a computer function that can only compute it when the range.. obvious solution is something like #include cmath float sin float x return limited_sin x M_PI 2 M_PI M_PI Why doesn't this..
