cool thanks. I know your not really supposed to read those documents but implementations, and actually why and how things happen fascinate me, It's why I love science, and have a fetish with the command prompt.
That strtod function was way more thought out than mine, but the fact they used 'while' statements in areas 'for' statements should really have been used will bother me for all time now. And how they could've made it 4 bytes smaller.
EDIT: do you know where stdlib.h is located in the computer? I get a few in spotlight, but they aren't the same file
