explain_strtod_or_die - convert string to number and report errors
#include <libexplain/strtod.h>
double explain_strtod_or_die(const char *nptr, char **endptr);
double explain_strtod_on_error(const char *nptr, char **endptr))
The explain_strtod_or_die function is used to call the strtod(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_strtod(3) function, and then the process terminates by calling exit(EXIT_FAILURE).
The explain_strtod_on_error function is used to call the strtod(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_strtod(3) function, but still returns to the caller.
The explain_strtod_or_die function only returns on success, see strtod(3) for more information. On failure, prints an explanation and exits, it does not return.
The explain_strtod_on_error function always returns the value return by the wrapped strtod(3) system call.
The explain_strtod_or_die function is intended to be used in a fashion similar to the following example:
double result = explain_strtod_or_die(nptr, endptr);
