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.
