# ^ Operator (Visual Basic)

**Visual Studio 2015**

Raises a number to the power of another number.

number ^ exponent

*number*Required. Any numeric expression.

*exponent*Required. Any numeric expression.

The result is *number* raised to the power of *exponent*, always as a **Double** value.

**Double**. Operands of any different type are converted to **Double**.

Visual Basic always performs exponentiation in the Double Data Type (Visual Basic).

The value of *exponent* can be fractional, negative, or both.

When more than one exponentiation is performed in a single expression, the **^** operator is evaluated as it is encountered from left to right.

## Example

The following example uses the **^** operator to raise a number to the power of an exponent. The result is the first operand raised to the power of the second.

Dim exp1, exp2, exp3, exp4, exp5, exp6 As Double exp1 = 2 ^ 2 exp2 = 3 ^ 3 ^ 3 exp3 = (-5) ^ 3 exp4 = (-5) ^ 4 exp5 = 8 ^ (1.0 / 3.0) exp6 = 8 ^ (-1.0 / 3.0)

The preceding example produces the following results:

exp1 is set to 4 (2 squared).

exp2 is set to 19683 (3 cubed, then that value cubed).

exp3 is set to -125 (-5 cubed).

exp4 is set to 625 (-5 to the fourth power).

exp5 is set to 2 (cube root of 8).

exp6 is set to 0.5 (1.0 divided by the cube root of 8).

Note the importance of the parentheses in the expressions in the preceding example. Because of

operator precedence, Visual Basic normally performs the^operator before any others, even the unary–operator. If exp4 and exp6 had been calculated without parentheses, they would have produced the following results:exp4 = -5 ^ 4 would be calculated as –(5 to the fourth power), which would result in -625.

exp6 = 8 ^ -1.0 / 3.0 would be calculated as (8 to the –1 power, or 0.125) divided by 3.0, which would result in 0.041666666666666666666666666666667.
