Use arithmetic operators to perform calculations in X++. Except for ~, which is unary, all arithmetic operators are dyadic; that is, they work on two operands. The syntax of arithmetic expressions is: expression1 ArithmeticOperator expression2.
| Operator | Term | Description |
|---|---|---|
| << | Left shift | Performs expression2 left shift (a multiplication by 2) on expression1. |
| >> | Right shift | Performs expression2 right shift (a division by 2) on expression1. |
| * | Multiply | Multiplies expression1 by expression2. |
| / | Divide | Divides expression1 by expression2. |
| DIV | Integer division | Performs an integer division of expression1 by expression2. |
| MOD | Integer remainder | Returns the remainder of an integer division of expression1 by expression2. |
| ~ | Not | Unary operator. Performs a binary not-operation. |
| & | Binary AND | Performs a binary and-operation on expression1 and expression2. |
| ^ | Binary XOR | Performs a binary XOR-operation on expression1 and expression2. |
| | | Binary OR | Performs a binary or-operation on expression1 and expression2. |
| + | Plus | Adds expression1 to expression2. |
| - | Minus | Subtracts expression2 from expression1. |
| ? | Ternary operator | Takes three expressions: expression1 ? expression2 : expression3. If expression1 is true, expression2 is returned; otherwise, expression3 is returned. |
| Operator | Example | Description |
|---|---|---|
| << | i = 1 << 4; | Performs 4 left shifts on 1 (1*2*2*2*2). This gives: i=16. |
| >> | i = 16 >> 4; | Performs 4 right shifts on 16 (16/2/2/2/2). This gives i=1. |
| * | i = 4*5; | Multiplies 4 by 5. i=20. |
| / | i = 20/5; | Divides 20 by 5. i=4. |
| div | i = 100 div 21; | Returns the integer division of 100 by 21. i=4 (4*21 = 84, remainder 16). |
| mod | i = 100 mod 21; | Returns the remainder of the integer division of 100 by 21. i=16. |
| ~ | i = ~1; | Binary negates 1. This gives i=-2 (all bits are reversed). |
| & | i = 1 & 3; | Binary AND. Return the bits in common in the two integers. i=1. |
| | | i = 1 | 3; | Binary OR. Return the bits set in either 1 or 3. i=3. |
| ^ | i = 1 ^ 3; | Binary XOR. Returns the bits set in 1 and NOT in 3 and vice versa. i=2. |
| + | i = 1 + 3; | Adds 1 and 3. i=4. |
| - | i = 3 - 1; | Subtracts 1 from 3. i=2. |
| ? | i = (400>4) ? 1 : 5; | If (400>4) 1 is returned, else 5 is returned. As 400>4, 1 is returned. i=1. |
