Operators
There are seven major types of mathematical operator, and four major types of bitwise operator.
Mathematical operators
Operation | Character used | Description | Example |
---|---|---|---|
Addition | Performed using the "+" operator | Adds values together. | A + B = 12 |
Subtraction | Performed using the "-" operator | Subtracts values. | A - B = 8 |
Multiplication | Performed using the "*" operator | Multiplies values together. | A * B = 20 |
Division | Performed using the "/" operator | Divides values. | S / B = 5 |
Increment | Performed using the "++" operator | Adds 1 to a variable and saves the variable. | A++ = 11 |
Decrement | Performed using the "--" operator | Subtracts 1 from a variable and saves the variable. | B-- = 9 |
Modulus | Performed using the "%" operator | Finds the remainder of a division between values. | 10 % 3 = 1 |
Note: there are variations on the increment and decrement operators. These can be performed in both prefix and postfix forms. In prefix form, (syntax "++x;") the variable will be incremented or decremented, and then the value will be used by the function calling it. In postfix form, however, (syntax "x++;") the variable will be used by the function calling it, and be incremented or decremented afterwards.
Comparison Operators
Operation | Character used | Description | Example |
---|---|---|---|
Equal | Performed using == | Returns true if both inputs are the same. | value == "test" |
Not Equal | performed using != | returns true if both inputs are not the same | value != "test" |
Less Than | Performed using < | Returns true if value 1 is less than or equal to value 2. | value < 0 |
Greater Than | performed using > | Returns true if value 1 is greater than value 2. | value > 1 |
Less Than or Equal | Performed using <= | Returns true if value 1 is less than or equal to value 2. | value <= 0 |
Greater Than or Equal | performed using >= | Returns true if value 1 is greater than or equal to value 2. | value >= 1 |
Bitwise operators
Operation | Character used | Description | Example |
---|---|---|---|
AND | Performed using "&" or "&&" | Returns true if both inputs are true. | true && false = false |
OR | performed using "|" or "||" | returns true if one or both inputs are true. | true || false = true |
XOR | Performed using "^" | Returns true if both inputs are different. | true ^ false = true |
NOT | performed using "!" | Returns false if true, or true if false. | !true = false |
The "and" and "or" operators also have variants when combined with "not", known as "nand" and "nor", but these cannot be performed directly in C#. and instead must be performed by combining the "and"/"or" with the "not" function.
