^ operator
Used to raise a number to the power of an exponent.
Syntax
result=number^exponent
The ^ operator syntax has these parts:
| Part | Description |
|---|---|
| result | Required; any numeric variable. |
| number | Required; any numeric expression. |
| exponent | Required; any numeric expression. |
Remarks
A number can be negative only if exponent is an integer value. When more than one exponentiation is performed in a single expression, the ^ operator is evaluated as it is encountered from left to right.
Usually, the data type of result is a Double or a Variant containing a Double. However, if either number or exponent is a Null expression, result is Null.
Example
This example uses the ^ operator to raise a number to the power of an exponent.
Dim MyValue
MyValue = 2 ^ 2 ' Returns 4.
MyValue = 3 ^ 3 ^ 3 ' Returns 19683.
MyValue = (-5) ^ 3 ' Returns -125.
Note
For 64-bit users: Because the caret operator is used to create Long Long data types in a 64-bit environment, the VBA IDE may not interpret this operator correctly. To ensure proper interpretation, add a space character immediately before the caret as shown.
x=y^2 ' Will generate "expected )" from VBA IDE.
x=y ^2 ' Will be interpreted as x equals y squared.
