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 behavior is the same as
strtod(nptr, NULL);
except that atof() does not detect errors.
For an explanation of the terms used in this section, see attributes(7).
