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);

SEE ALSO
       strtof(3)
	       convert ASCII string to floating-point number

       explain_strtof(3)
	       explain strtof(3) errors
