| / | Division | a=21/3; | a=7 |
| % | Modulus | a=20%7; | a=6 |
| ++ | Increment | a++; | a=a+1 |
| -- | Decrement | a--; | a=a-1 |
Assignment
| Operator | Description | Example | Result |
|---|
| = | Assignment | a=8 | a=8; |
| += | Add rightside value to original value | a=1; a+=7; | a=8 |
| -= | Subtract rightside value from original value | a=8; a-=2; | a=6 |
| *= | Multiply rightside value to original value | a=8; a*=3; | a=24 |
| /= | Divide leftside value by rightside value | a=21; a/=3; | a=7 |
| %= | Same as divide, but output the modulus | a=20; a%=7; | a=6 |
