 DESCRIPTION
-	The function <<strtod>> parses the character string <[str]>,

+	<<strtod>>, <<strtof>>, <<strtold>> parse the character string
+	<[str]>, producing a substring which can be converted to a double,

+	first non-whitespace character, that has one of these formats:

 	(which will contain at least the terminating null character of
 	<[str]>) is stored in <<*<[tail]>>>.  If you want no
 	assignment to <<*<[tail]>>>, pass a null pointer as <[tail]>.
-	<<strtof>> is identical to <<strtod>> except for its return type.
 
 	This implementation returns the nearest machine number to the
 	input decimal string.  Ties are broken by using the IEEE
 	round-even rule.  However, <<strtof>> is currently subject to
 	double rounding errors.
 
+	<<strtod_l>>, <<strtof_l>>, <<strtold_l>> are like <<strtod>>,
+	<<strtof>>, <<strtold>> but perform the conversion based on the
+	locale specified by the locale object locale.  If <[locale]> is
+	LC_GLOBAL_LOCALE or not a valid locale object, the behaviour is
+	undefined.
+
 	The alternate function <<_strtod_r>> is a reentrant version.
 	The extra argument <[reent]> is a pointer to a reentrancy structure.
 
 RETURNS
-	<<strtod>> returns the converted substring value, if any.  If
-	no conversion could be performed, 0 is returned.  If the
-	correct value is out of the range of representable values,
-	plus or minus <<HUGE_VAL>> is returned, and <<ERANGE>> is
-	stored in errno. If the correct value would cause underflow, 0
-	is returned and <<ERANGE>> is stored in errno.
+	These functions return the converted substring value, if any.  If
+	no conversion could be performed, 0 is returned.  If the correct
+	value is out of the range of representable values, plus or minus
+	<<HUGE_VAL>> (<<HUGE_VALF>>, <<HUGE_VALL>>) is returned, and
+	<<ERANGE>> is stored in errno. If the correct value would cause
+	underflow, 0 is returned and <<ERANGE>> is stored in errno.
+
+PORTABILITY
+<<strtod>> is ANSI.
+<<strtof>>, <<strtold>> are C99.
+<<strtod_l>>, <<strtof_l>>, <<strtold_l>> are GNU extensions.
