Scala 4 Multiply AND assignment operator, It multiplies right operand with the left operand and assign the result to left operand Ex: C *= A is equivalent to C = C * A /= (Divide and Assignment) 5 Divide AND assignment operator, It divides left operand with the right operand and assign the result to left operand Ex: C /= A is equivalent to C = C / A %= (Modulus and Assignment) 6 Modulus AND assignment operator, It takes modulus using two operands and assign the result to left operand Ex: C %= A is equivalent to C = C % A > 2 &= (Bitwise AND assignment) 9 Bitwise AND assignment operator Ex: C &= 2 is same as C = C & 2 ^= (bitwise exclusive OR and assignment) 10 bitwise exclusive OR and assignment operator Ex: C ^= 2 is same as C = C ^ 2 |= (bitwise inclusive OR and assignment) 11 bitwise inclusive OR and assignment operator Ex: C |= 2 is same as C = C | 2 43
