Python get_c_string Examples

Example #1

    def __int__(self):
        # buf will contain the integer encoded in decimal plus the trailing
        # zero, and possibly the negative sign.
        # dig10(x) < log10(x) + 1 = log2(x)/log2(10) + 1 < log2(x)/3 + 1
        buf_len = _gmp.mpz_sizeinbase(self._mpz_p, 2) // 3 + 3
        buf = create_string_buffer(buf_len)

        _gmp.gmp_snprintf(buf, c_size_t(buf_len), b"%Zd", self._mpz_p)
        return int(get_c_string(buf))

        _gmp.gmp_snprintf(buf, c_size_t(buf_len), b("%Zd"), self._mpz_p)
        return int(get_c_string(buf))
