The JavaScript Math object used to perform mathematical tasks with numbers.`Math`

is an object that has properties and methods.

`Math`

has no constructor. All `Math’s`

properties and methods are static.

To refer methods and properties use Math.propertName and functions as Math.funcationName().

For example to access the constant pi use `Math.PI`

` To`

call the sine function use `Math.sin(valuex)`

, where `valuex`

is a argument. Constants are defined with the full precision of real numbers.

The math object provide properties and methods of constants and functions for mathematical.

Math’s properties and methods can be called by using Math as an object without creating it.

**Syntax**

1 2 | Math.propertyName Math.functionName() |

Example

1 2 | Math.PI Math.sin(50); |

1 2 3 4 5 6 7 8 9 | <html> <body> <p id="piValue"></p> <script> document.getElementById("piValue").innerHTML = Math.PI; </script> </body> </html> |
