# ^ Operator (Visual Basic)

**Visual Studio 2005**

Raises a number to the power of another number.

number ^ exponent

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.

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.
