Web14 nov. 2024 · An operator is unary if it has a single operand. For example, the unary negation - reverses the sign of a number: let x = 1; x = -x; alert( x ); // -1, unary negation was applied. An operator is binary if it has two operands. The same minus exists in binary form as well: let x = 1, y = 3; alert( y - x ); // 2, binary minus subtracts values. Web25 apr. 2016 · Negating a number means changing its sign to the opposite sign, so Attaching a minus sign to a positive number makes it negative. Attaching a minus sign to a negative number makes it positive. The two adjacent (side-by-side) minus signs cancel each other out. Attaching a minus sign to 0 doesn’t change its value, so –0 = 0.
