NAME

       wcstod(), wcstof(), wcstold() - convert a wide character string to a double-precision number

SYNOPSIS

   Itanium(R)-based Systems Only
   Remarks
       These  functions  are  compliant with the UNIX standard Worldwide Portability Interface wide-character formatting functions.  They parallel
       the 8-bit character formatting functions defined in strtod(3C), strtold(3C) and strtof(3C) respectively.

DESCRIPTION

       The and functions return the value represented by the wide-character string pointed to by nptr as a double-precision floating-point number,
       single-precision  floating-point  number,  and  long  double-precision number, respectively.  The wide character string is scanned (leading
       white-space characters as defined by in wctype(3C) are ignored) up to the first unrecognized character.	If no conversion can  take  place,
       zero is returned.

       The and functions recognize wide characters in the following sequence:

	      1.      An optional string of white space wide characters, which are ignored
	      2.      An optional sign followed by one of the following:
		      o      A	string	of  digits  optionally	containing  a radix character, then an optional or followed by an optional sign or
			     space, followed by an integer
		      o      A 0x or 0X, then a non-empty sequence of hexadecimal digits optionally containing a radix character, then an optional
			     binary exponent part
		      o    One of INF or INFINITY, or any other wide string equivalent except for case
		      o    One of NAN or NAN(n-wchar-sequence), or any other wide string ignoring case in the NAN part, where n-wchar-sequence is:
			   o  digit
			   o  nondigit
			   o  n-wchar-sequence digit
			   o  n-wchar-sequence nondigit

       The  radix  character is determined by the current environment (see setlocale(3C)).  If has not been called successfully, the default envi-
       ronment, "C", is used (see lang(5)).  The default environment specifies a period (.) as the radix character.

       If the value of endptr is not the variable to which it points is set to point at the wide character after the last number, if any, that was
       recognized.  If no number can be formed, is set to nptr, and zero is returned.

EXTERNAL INFLUENCES

   Environment Variables
       determines the value of the radix character within the currently loaded environment.

       determines how wide character codes are interpreted.

   International Code Set Support
       Single- and multibyte character code sets are supported.

RETURN VALUE

       If the correct value would cause overflow, or is returned (according to the sign of the value), and is set to

       If the correct value would cause underflow, zero is returned and is set to

       If  encounters  an  input  wide	character  string equal to or (both case insensitive) it will return If encounters an input wide character
       string equal to or (both case insensitive) it will return
