| Operator | Description | Example | Result |
|---|---|---|---|
| + | Addition 加 | x=2 y=2 x+y | 4 |
| - | Subtraction 减 | x=5 y=2 x-y | 3 |
| * | Multiplication 乘 | x=5 y=4 x*y | 20 |
| / | Division 除 | 15/5 5/2 | 3 2.5 |
| % | Modulus (division remainder) 余数 | 5%2 10%8 10%2 | 1 2 0 |
| ++ | Increment 递增 | x=5 x++ | x=6 |
| -- | Decrement 递减 | x=5 x-- | x=4 |
| Operator | Example | Is The Same As |
|---|---|---|
| = | x=y | x=y |
| += | x+=y | x=x+y |
| -= | x-=y | x=x-y |
| *= | x*=y | x=x*y |
| /= | x/=y | x=x/y |
| %= | x%=y | x=x%y |
| Operator | Description | Example |
|---|---|---|
| == | is equal to 等于 | 5==8 returns false |
| === | is equal to (checks for both value and type) 等于（检查值和类型）*全吻合才算相等 | x=5 y="5" x==y returns true |
| != | is not equal 不等于 | 5!=8 returns true |
| > | is greater than 大于 | 5>8 returns false |
| < | is less than 小于 | 5<8 returns true |
| >= | is greater than or equal to 大于等于 | 5>=8 returns false |
