   Where can I find the math.h sin() and cos() bodies?!?
  I wanna know how these functions are inside...how are they structured? how is the Taylor series implemented inside of them? thanks.. ;)   
  Do you just want a good way to compute these or do you really want to see how your compiler implements them? If it's the second: Use a disassembler.   ;  It is the second...I'm not experienced within assembly :P ...I think it will be hard for me understand . . . I would like to see C++ code. It is just a curiosity.thanks   ;  I'm not sure if there is a C++ body, the MinGW g++ compiler seems to use a function written in assembly that just uses the FSIN instruction to do the real work.   ;  Yeah. There are instructions like 'fsin' and 'fcos', so the answer to "where is it implemented" is "in the transistors on the cpu". :)
