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.
