Arithmetical Operations

Operator

Operand/

Data Type

Results In Data Type

Description

++, -- (as prefix, e.g. ++i)

int

int

Adds/subtracts 1 to/from the value of the operand. Superior expressions are evaluated after the value of the operand is changed.

++, -- (as suffix, e.g. i++)

int

int

Adds/subtracts 1 to/from the value of the operand. Superior expressions are evaluated before the value of the operand is changed.

+

int, float, string

Depends on operand data types. It will be converted into the more precise data type.

Calculates the sum of two operands or concatenates two character strings.

-, *, /

int, float

Depends on operand data types. It will be converted into the more precise data type.

Calculates the difference/product/quotient of two operands.

%

int

int

Calculates the remainder of an integer division.

 

Logical Operations

Operator

Operand/

Data Type

Results In Data Type

Description

!

bool

bool

This is the logical NOT. It negates the following operand.

||

bool

bool

This is the logical OR. The result is true if at least one operand is true. Both operands are evaluated in every single case.

&&

bool

bool

This is the logical AND. The result is true if both operands are true. Both operands are evaluated in every single case.

<, <=, >, >=, ==, !=

int, float, bool, string

bool

Compares two operands.

 

Bit Operations

Operator

Operand/

Data Type

Results In Data Type

Description

~

int

int

This is the bitwise NOT. It negates each bit of the following operand.

^

int

int

This is the bitwise XOR. Each bit of the result is set where the corresponding bits of the operands are different.

|

int

int

This is the bitwise OR. Each bit of the result is set where at least one of the corresponding bits of the operands is set.

&

int

int

This is the bitwise AND. Each bit of the result is set where both corresponding bits of the operands are set.

<<

int

int

Shifts the bits of the first operand by offset n to the left (n is the second operand). The rightmost (least significant) bits of the result are set to 0.

>>

int

int

Shifts the bits of the first operand by offset n to the right (n is the second operand). The leftmost (most significant) bits of the result are set to 0.

>>>

int

int

Shifts the bits of the first operand by offset n to the right (n is the second operand). The leftmost (most significant) bits of the result  depend on the first operand which sign is preserved (i.e. negative numbers will not become positive by shifting to the right).

 

Assignment Operations

Operator

Description

=

A simple assignment. The left operand gets the value of the right one.

+=

For example: i += 4 corresponds to i = i + 4.

-=

For example: i -= 4 corresponds to i = i - 4.

*=

For example: i *= 4 corresponds to i = i * 4.

/=

For example: i /= 4 corresponds to i = i / 4.

%=

For example: i %= 4 corresponds to i = i % 4.

^=

For example: i ^= 4 corresponds to i = i ^ 4.

|=

For example: i |= 4 corresponds to i = i | 4.

&=

For example: i &= 4 corresponds to i = i & 4.

<<=

For example: i <<= 4 corresponds to i = i << 4.

>>=

For example: i >>= 4 corresponds to i = i >> 4.

>>>=

For example: i >>>= 4 corresponds to i = i >>> 4.
