atof - convert a string to a double.
#include <stdlib.h> double atof(const char *nptr);
The atof() function converts the initial portion of the string pointed to by nptr to double. The behaviour is the same as strtod(nptr, (char **)NULL); except that atof() does not detect errors.
The converted value.
