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