# pow2

Base 2 exponentiation and scaling of floating-point numbers.

## Syntax

* Y = pow2(E)
* Y = pow2(X, E)

## Input argument

* E - Exponent values
* X - Significand values

## Output argument

* Y - result of pow2.

## Description

**Y = pow2(E)** computes 2 to the power of **E**.

**Y = pow2(X, E)** computes X times 2 to the power of **E**.

## Example
