Go operators are built into the language:
算术运算符
关系运算符
逻辑运算符
位运算符
赋值运算符
Arithmetic operators 1.1
| Operators |
description |
| + |
Adding |
| - |
Subtraction |
| * |
Multiplied |
| / |
Divided |
| % |
Remainder |
Note: ++ (increment) and - (decrement) Go is a single statement in the language, not the operator.
1.2. 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, returns True if it is otherwise False. |
| <= |
Check the left value is less than or equal to the right value, returns True if it is otherwise False. |
1.3. Logical Operators
| Operators |
description |
| && |
Logical AND operator. If both sides of the operands are True, compared to True, otherwise False. |
| ll |
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. |
1.4. Bitwise operator
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) |
| l |
Two involved in computing the number corresponding to each phase, or binary. (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 2 ^ n. "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. |
1.5. Assignment operator
| Operators |
description |
| = |
Simple assignment operator, the value of the expression of a value assigned to a left |
| += |
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 |
| l= |
After pressing position or assignment |
| ^= |
按位异或后赋值 |
