An intrinsic object that provides basic mathematics functionality and constants.

## Syntax

```
Math.[{property | method}]
```

## Parameters

*property*

Required. Name of one of the properties of the **Math**. object.

*method*

Required. Name of one of the methods of the **Math**. object.

## Remarks

The **Math** object cannot be created using the **new** operator, and gives an error if you attempt to do so. The scripting engine creates it when the engine is loaded. All of its methods and properties are available to your script at all times.

## Requirements

The `Math`

object was introduced in Internet Explorer before Internet Explorer 6.

## Constants

The following table lists the constants of the `Math`

object.

Constant | Description |
---|---|

Math.E Constant | The mathematical constant e. This is Euler's number, the base of natural logarithms. |

Math.LN2 Constant | The natural logarithm of 2. |

Math.LN10 Constant | The natural logarithm of 10. |

Math.LOG2E Constant | The base-2 logarithm of e. |

Math.LOG10E Constant | The base-10 logarithm of e. |

Math.PI Constant | Pi. This is the ratio of the circumference of a circle to its diameter. |

Math.SQRT1_2 Constant | The square root of 0.5, or, equivalently, one divided by the square root of 2. |

Math.SQRT2 Constant | The square root of 2. |

## Functions
