#include <sicstus/sicstus.h> int SP_get_number_codes(SP_term_ref term, char const **s);
*s a zero-terminated array of characters
corresponding to the printed representation of a Prolog number. The
array is subject to reuse by other support functions, so if the value is
going to be used on a more than temporary basis, it must be moved
Zero if the conversion fails (as far as failure can be detected), and a nonzero value otherwise.
