stdlib: add and test strtod, strtof and atof (DONE) This uses a generic function strto_fp similar to strto_int that is used for strtol and its derivatives. 2021-05-21 23:52:54 +02:00			`#include "stdlib_p.h"`

stdlib: formatting on the strto* functions * Name the private function __strto_{int,fp} (with leading double underscores) to avoid name conflicts * Fix comments of the wrong style * Fix missing leading double underscores in stdlib_p.h 2021-05-24 10:07:48 +02:00			`int err = __strto_fp(ptr, endptr, NULL, &f, NULL);`
