NAME
       explain_strtof_or_die - convert string to number and report errors


SYNOPSIS
       #include <libexplain/strtof.h>
       float explain_strtof_or_die(const char *nptr, char **endptr);
       float explain_strtof_on_error(const char *nptr, char **endptr))


DESCRIPTION
       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.

       nptr    The nptr, exactly as to be passed to the strtof(3) system call.

       endptr  The endptr, exactly as to be passed to the strtof(3) system call.


RETURN VALUE
       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.


EXAMPLE
       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);
