NAME
       ustrtod	- Converts a string into a floating point number. Allegro game
       programming library.

SYNOPSIS
       #include <allegro.h>

       double ustrtod(const char *s, char **endp);

DESCRIPTION
       This function converts as many characters  of  `s'  that	 look  like  a
       floating	 point number into one, and sets `*endp' to point to the first
       unused character, if `endp' is not a NULL pointer. Example:

	  char *endp, *string = "456.203 askdfg";
	  double number = ustrtod(string, &endp);

RETURN VALUE
       Returns the string converted as a value of type	`double'.  If  nothing
       was converted, returns zero with *endp pointing to the beginning of s.
