VBScript - Operators

讓我們假設一個表達式4+5等於9。這裡，4和5稱爲操作數，而+稱爲運算符。VBScript語言支持以下類型的運算符−

The Arithmetic Operators

VBScript支持以下算術運算符−

假設變量A爲5，變量B爲10，則-;

Operator	Description	Example
+	Adds two operands	A + B will give 15
-	Subtracts second operand from the first	A - B will give -5
*	Multiply both operands	A * B will give 50
/	Divide numerator by denumerator	B / A will give 2
%	Modulus Operator and remainder of after an integer division	B MOD A will give 0
^	Exponentiation Operator	B ^ A will give 100000

VBScript語言支持以下比較運算符−

假設變量A爲10，變量B爲20，則-;

Operator	Description	Example
=	Checks if the value of two operands are equal or not, if yes then condition becomes true.	(A == B) is False.
<>	Checks if the value of two operands are equal or not, if values are not equal then condition becomes true.	(A <> B) is True.
>	Checks if the value of left operand is greater than the value of right operand, if yes then condition becomes true.	(A > B) is False.
<	Checks if the value of left operand is less than the value of right operand, if yes then condition becomes true.	(A < B) is True.
>=	Checks if the value of left operand is greater than or equal to the value of right operand, if yes then condition becomes true.	(A >= B) is False.
<=	Checks if the value of left operand is less than or equal to the value of right operand, if yes then condition becomes true.	(A <= B) is True.

VBScript語言支持以下邏輯運算符−

假設變量A保持10，變量B保持0，然後&負;

Operator	Description	Example
AND	Called Logical AND operator. If both the conditions are True, then Expression becomes True.	a<>0 AND b<>0 is False.
OR	Called Logical OR Operator. If any of the two conditions is True, then condition becomes True.	a<>0 OR b<>0 is true.
NOT	Called Logical NOT Operator. It reverses the logical state of its operand. If a condition is True, then the Logical NOT operator will make it False.	NOT(a<>0 OR b<>0) is false.
XOR	Called Logical Exclusion. It is the combination of NOT and OR Operator. If one, and only one, of the expressions evaluates to True, result is True.	(a<>0 XOR b<>0) is true.

VBScript語言支持以下連接運算符−

假設變量A爲5，變量B爲10，則-;

顯示示例

Operator	Description	Example
+	Adds two Values as Variable Values are Numeric	A + B will give 15
&	Concatenates two Values	A & B will give 510

假設變量A=「Microsoft」和變量B=「VBScript」，然後−

Operator	Description	Example
+	Concatenates two Values	A + B will give MicrosoftVBScript
&	Concatenates two Values	A & B will give MicrosoftVBScript

注意−連接運算符可用於數字和字符串。如果變量包含數值或字符串值，則輸出取決於上下文。
