Function opcodeNumEqualVerify

txscript/opcode.go:1656–1662

opcodeNumEqualVerify is a combination of opcodeNumEqual and opcodeVerify. Specifically, treats the top two items on the data stack as integers. When they are equal, they are replaced with a 1, otherwise a 0. Then, it examines the top item on the data stack as a boolean value and verifies it evalu

(op *opcode, data []byte, vm *Engine)

//
// Stack transformation: [... x1 x2] -> [... bool] -> [...]
func opcodeNumEqualVerify(op *opcode, data []byte, vm *Engine) error {
	err := opcodeNumEqual(op, data, vm)
	if err == nil {
		err = abstractVerify(op, vm, ErrNumEqualVerify)
	}
	return err
}

// opcodeNumNotEqual treats the top two items on the data stack as integers.
// When they are NOT equal, they are replaced with a 1, otherwise a 0.
