Arithmetic

+

x + y

Adds x and y.

-

x - y

Subtracts y from x.

*

x * y

Multiplies x by y.

/

x / y

Divides x by y.

%

x % y

Returns the remainder of integer division of x and y.

Logical (Boolean and bitwise)

&

x & y

Evaluates both x and y and returns the logical conjunction ("AND") of their results. If x and y are integers, the logical conjunction is performed bitwise.

|

x | y

Evaluates x and y and returns the logical disjunction ("OR") of their results. If x and y are integers, the logical disjunction is performed bitwise.

^

x ^ y

Returns the exclusive or ("XOR") of their results. If x and y are integers, the exclusive or is performed bitwise.

!

!x

Evaluates x and returns the negation ("NOT") of the result.

• If x evaluates to false, it returns true.
• If x evaluates to true, it returns false.

~

~x

Evaluates x and returns the bitwise negation of the result. ~x returns a value where each bit is the negation of the corresponding bit in the result of evaluating x.

&&

x && y

Evaluates x.

• If the result is false, it returns false.
• Otherwise, it evaluates and returns the results of y.

Note that if evaluating y would hypothetically have no side effects, the results are identical to the logical conjunction performed by the & operator.

||

x || y

Evaluates x.

• If the result is true, it returns true.
• Otherwise, it evaluates and returns the results of y.

Note that if evaluating y would hypothetically have no side effects, the results are identical to the logical disjunction performed by the | operator.

( )

Used to group information.

String concatenation

+

x + y

Concatenates strings.

Relational

==

x == y

• If x and y have the same value, it returns true.
• Otherwise, it returns false.

!=

x != y

Returns the logical negation of the operator ==.

• If x is not equal to y, it returns true.
• If x is equal to y, it returns false.

<

x < y

• If x is less than y, it returns true.
• Otherwise, it returns false.

>

x > y

• If x is greater than y, it returns true.
• Otherwise, it returns false.

<=

x <= y

• If x is less than or equal to y, it returns true.
• Otherwise, it returns false.

>=

x >= y

• If x is greater than or equal to y, it returns true.
• Otherwise, it returns false.

Member access

.

this.Value

Used to form long names.

Indexing

[ ]

Used to access array elements.

Conditional

?:

x ? y : z

• If x is true, it returns y.
• Otherwise, it returns z.

Assignment

=

x = y

Assigns the value of y to x.
