Say I want to look into the details of how a function works because I have been trying to come up with my own version of it and it is falling short.. how would I do that?
For example the atof() function. I have been trying to write my own function to convert a string into a floating point value and am running into difficulties. I know the atof() function can do it for me, but I can't find anywhere the details of how that function actually works. Any sites you can direct me to?
