Verilog Arithmetic Operators

Operator	Description
a + b	a plus b
a - ​b	a minus b
a * b	a multiplied by b
a / b	a divided by b
a % b	a modulo b
a ** b	a to the power of b

​

a = 5 b = 10 c = 1 d = Z

Character	Operation performed	Example	Type
+	Add	b + c = 11	Binary
-	Subtract	b - c = 9	Binary
/	Divide	b / a = 2	Binary
* **	Multiply, power	a * b = 50, a**b	Binary
%	Modulus	b % a = 0	Binary
%=	Modulus assignment	a %= b ( a = a % b)	Binary
+= -= /= *=	Arithmethic assignment	a += b ( a = a + b) a += 2 (a = a + 2)	Unary
++ --	Unary increment	a = b++ ( a = b, b = b + 1) a = ++b ( b = b + 1, a = b)	Unary
