## Definition and Usage

The exp() method returns the value of E^{x}, where E is Euler's constant (approximately 2.7183) and x is the number passed to it.

## Syntax

Math.exp(x) |

Parameter | Description |
---|---|

x | Required. A number |

## Tips and Notes

**Tip:**E is the Euler's constant, which is the base of natural logarithms (approximately 2.7183).

## Example

In the following example we will use the exp() method on different numbers:<script type="text/javascript"> document.write(Math.exp(1) + "<br />"); document.write(Math.exp(-1) + "<br />"); document.write(Math.exp(5) + "<br />"); document.write(Math.exp(10) + "<br />"); </script> |

The output of the code above will be:

2.718281828459045 0.36787944117144233 148.4131591025766 22026.465794806718 |
