Arithmetic operators apply standard mathematical operations to their operands.


Operator Operator name Example Result
+ unary plus +a the value of a
- unary minus -a the negative of a
+ addition a + b the addition of a and b
- subtraction a - b the subtraction of b from a
* product a * b the product of a and b
/ division a / b the division of a by b
% modulo a % b the remainder of a divided by b
~ bitwise NOT ~a the bitwise NOT of a
& bitwise AND a & b the bitwise AND of a and b
| bitwise OR a | b the bitwise OR of a and b
^ bitwise XOR a ^ b the bitwise XOR of a and b
<< bitwise left shift a << b a left shifted by b
>> bitwise right shift a >> b a right shifted by b
