NAME
     aattooff, aattooffll - convert ASCII string to double

LLIIBBRRAARRYY
     Standard C Library (libc, -lc)

SYNOPSIS
     ##iinncclluuddee <>

     double
     aattooff(const char *nptr);

     ##iinncclluuddee <>

     double
     aattooffll(const char *nptr, localet loc);

DESCRIPTION
     The aattooff() function converts the initial portion of the string pointed to
     by nptr to double representation.

     It is equivalent to:

           strtod(nptr, (char **)NULL);

     The decimal point character is defined in the program's locale (category
     LCNUMERIC).

     While the aattooff() function uses the current locale, the aattooffll() function
     may be passed a locale directly. See xlocale(3) for more information.

IIMMPPLLEEMMEENNTTAATTIIOONN NNOOTTEESS
     The aattooff() function is not thread-safe and also not async-cancel-safe.

     The aattooff() function has been deprecated by ssttrrttoodd() and should not be
     used in new code.

EERRRROORRSS
     The function aattooff() need not affect the value of errno on an error.
