.NET Framework 4.5

Returns a specified number raised to the specified power.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

## Syntax

```static member Pow :
x:float *
y:float -> float
```

#### Parameters

x
Type: System.Double

A double-precision floating-point number to be raised to a power.

y
Type: System.Double

A double-precision floating-point number that specifies a power.

#### Return Value

Type: System.Double
The number x raised to the power y.

## Remarks

The following table indicates the return value when various values or ranges of values are specified for the x and y parameters. For more information, see Double.PositiveInfinity, Double.NegativeInfinity, and Double.NaN.

Parameters

Return value

x or y = NaN.

NaN

x = Any value except NaN; y = 0.

1

x = NegativeInfinity; y < 0.

0

x = NegativeInfinity; y is a positive odd integer.

NegativeInfinity

x = NegativeInfinity; y is positive but not an odd integer.

PositiveInfinity

x < 0 but not NegativeInfinity; y is not an integer, NegativeInfinity, or PositiveInfinity.

NaN

x = -1; y = NegativeInfinity or PositiveInfinity.

NaN

-1 < x < 1; y = NegativeInfinity.

PositiveInfinity

-1 < x < 1; y = PositiveInfinity.

0

x < -1 or x > 1; y = NegativeInfinity.

0

x < -1 or x > 1; y = PositiveInfinity.

PositiveInfinity

x = 0; y < 0.

PositiveInfinity

x = 0; y > 0.

0

x = 1; y is any value except NaN.

1

x = PositiveInfinity; y < 0.

0

x = PositiveInfinity; y > 0.

PositiveInfinity

## Examples

The following example uses the Pow method to calculate the value that results from raising 2 to a power ranging from 0 to 32.

No code example is currently available or this language may not be supported.

The example displays output like the following:

```       20 = 1 (0x1)
21 = 2 (0x2)
22 = 4 (0x4)
23 = 8 (0x8)
24 = 16 (0x10)
25 = 32 (0x20)
26 = 64 (0x40)
27 = 128 (0x80)
28 = 256 (0x100)
29 = 512 (0x200)
210 = 1,024 (0x400)
211 = 2,048 (0x800)
212 = 4,096 (0x1000)
213 = 8,192 (0x2000)
214 = 16,384 (0x4000)
215 = 32,768 (0x8000)
216 = 65,536 (0x10000)
217 = 131,072 (0x20000)
218 = 262,144 (0x40000)
219 = 524,288 (0x80000)
220 = 1,048,576 (0x100000)
221 = 2,097,152 (0x200000)
222 = 4,194,304 (0x400000)
223 = 8,388,608 (0x800000)
224 = 16,777,216 (0x1000000)
225 = 33,554,432 (0x2000000)
226 = 67,108,864 (0x4000000)
227 = 134,217,728 (0x8000000)
228 = 268,435,456 (0x10000000)
229 = 536,870,912 (0x20000000)
