C++ (Cpp) fp_rsh1_low Examples

Example #1

File: relic_fp_add_low.c Project: Arash-Afshar/relic

void fp_hlvd_low(dig_t *c, const dig_t *a) {
	dig_t carry = 0;

	if (a[0] & 1) {
		carry = fp_addn_low(c, a, fp_prime_get());
	} else {
		fp_copy(c, a);
	}

	fp_add1_low(c + FP_DIGS, a + FP_DIGS, carry);

	carry = fp_rsh1_low(c + FP_DIGS, c + FP_DIGS);
	fp_rsh1_low(c, c);
	if (carry) {
		c[FP_DIGS - 1] ^= ((dig_t)1 << (FP_DIGIT - 1));
	}
}
