Language basis of Go Operators
Operator for performing mathematical or logical operations at runtime.
Operators
Go operators are built into the language:
- Arithmetic Operators
- Relational Operators
- Logical Operators
- Bitwise Operators
- Assignment Operators
Arithmetic operators
| Operators | description |
|---|---|
| + | Adding |
| - | Subtraction |
| * | Multiplied |
| / | Divided |
| % | Remainder |
Note: ++ (increment) and --(decrement) Go is a single statement in the language, not the operator.
Relational Operators
| Operators | description |
|---|---|
| == | Check the two values are equal, equal returns True if otherwise False. |
| != | Check the two values are not equal, not equal returns True if otherwise False. |
| > | Check the left value is greater than the right value, it returns True if it is otherwise False. |
| >= | Check the left value is greater than or equal to the right value, it returns True if it is otherwise False. |
| < | Check the left value is less than the right value, it returns True if it is otherwise False. |
| <= | Check the left value is less than or equal to the right value, it returns True if it is otherwise False. |
Logical Operators
| Operators | description |
|---|---|
| && | Logical AND operator. If both sides of the operands are True, compared to True, otherwise False. |
| || | Logical OR operator. If the number of operations on both sides of a True, compared to True, otherwise False. |
| ! | Logical NOT operator. If the condition is True, it was False, otherwise True. |
Bitwise Operators
Bitwise operators of integer bits in the memory operation.
| Operators | description |
|---|---|
| & | And two binary phase number corresponding to each of the participating operation. (Only two are 1 to 1) |
| | | Two involved in computing the number corresponding to the respective binary or phase. (Two have a 1 on 1) |
| ^ | Two involved in computing the number corresponding to the respective binary or different, when two dissimilar corresponding binary, the result is 1. (Two are not the same, compared with 1) |
| << | N-bit left shift is multiplied by the power of n 2. "A << b" is the whole of a respective binary b-bit left shift, the high discard, low 0s. |
| >> | Right by n bits is divided by 2 ^ n. "A >> b" is a whole to the right of each binary bit b. |
Assignment Operators
| Operators | description |
|---|---|
| = | Simple assignment operator, will assign a value of the expression of an lvalue |
| += | Added together before assignment |
| -= | After subtraction assignment |
| *= | By multiplying assignment |
| /= | Division after assignment |
| %= | Remainder after assignment |
| <<= | Left after the assignment |
| >>= | Right after the assignment |
| &= | Bitwise and after the assignment |
| |= | After pressing position or assignment |
| ^= | After pressing bit XOR assignment |
