Arithmetic Operators

Arithmetic operators perform calculations in X++. Arithmetic operators are used
like relational operators except for '~, ++, --, +=, and -='. The following table
defines available arithmetic operators:

Operator	Term	Description
+	Plus	Adds expression1 to expression2.
-	Minus	Subtracts expression2 from expression1.
*	Multiply	Multiplies expression1 with expression2.
/	Divide	Divides expression1 with expression2.
DIV	Integer division	Performs an integer division of expression1 with expression2.
MOD	Integer remainder	Returns the rest of an integer division of expression1 with 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.
<<	Left shift	Performs expression2 left shift (a multiplication with two) on expression1.
>>	Right shift	Performs expression2 right shift (a division by two) on expression1.
?	Ternary operator	Takes three expressions: expression1 ? expression2 : expression3. If expression1 is true, expression2 is returned otherwise expression3 is returned.

The following are some examples of these arithmetic operators. For all examples,
the variable 'i' is an integer.

Evaluated Expression	Return Value
i++;	Increments the i variable by one.
i--;	Decrements the i variable by one.
i += 2;	Increments the i variable by two every time.
i -= 3;	Decrements the i variable by three every time.
i = 3 << 3	i = 24 (i = 3*2*2*2)

i = 24 >> 2	i = 6 (i = 24/2/2)
i = 80 DIV 13	i = 6 (6 is the largest number that 13 can be multiplied by, where the result is less than or equal to 80. In this case, 6*13 = 78, remainder 2)
i = 80 MOD 13	i = 2 (2 is the remainder after dividing 80 by 13)

Guide. "
