Method Add

crypto/secp256k1/curve.go:132–135

Add returns the sum of (x1,y1) and (x2,y2).

(x1, y1, x2, y2 *big.Int)

// Add returns the sum of (x1,y1) and (x2,y2).
func (BitCurve *BitCurve) Add(x1, y1, x2, y2 *big.Int) (*big.Int, *big.Int) {
	z := new(big.Int).SetInt64(1)
	return BitCurve.affineFromJacobian(BitCurve.addJacobian(x1, y1, z, x2, y2, z))
}

// addJacobian takes two points in Jacobian coordinates, (x1, y1, z1) and
// (x2, y2, z2) and returns their sum, also in Jacobian form.
