JavaScript math Functions are built-in and static. They allow developers to implement not only basic mathematical operations but advanced calculations as well.

Working with JavaScript built-in math object can be highly useful, whether you want to build a calculator for your website or generate a random number for a guessing game. In this tutorial, you will learn to work with the JavaScript math object. You will learn all about its syntax, the most popular methods and properties.

**object**allows**mathematical****tasks**to be performed on numbers. - The JavaScript
**Math****object**includes**many****methods and properties**you can apply. - This object has
**no****constructor**and cannot be created first.

## Math Functions

In this chapter, we will present you with the most commonly used math functions. Each of them will be explained in a short and clear manner for you to grasp each concept quickly. Code examples will be helpful, too. If you wish to read more on math functions, don't hesitate to visit this tutorial we have created for easy referral.

#### Math.max() and Math.min()

You can use `Math.max()`

JavaScript to find the **highest** out of listed values, and `Math.min()`

to find the **lowest**:

#### Math.random()

`Math.random()`

will return a random numeric value between 0 (inclusive), and 1 (exclusive):

#### Math.round()

JavaScript `Math.round()`

is used to round a number to the nearest integer, up or down:

#### Math.ceil()

`Math.ceil()`

is used to round a number **up** to the nearest integer:

#### Math.floor()

JavaScript `Math.floor()`

is used to round a number **down** to the nearest integer:

## Get a Random Number

You can use `Math.random()`

and `Math.floor()`

together to get a random integer ranging from 0 to 10.

In the example below, `Math.random()`

generates a random decimal number between 0 and 1, which is multiplied by 10 to get a decimal number between 0 and 10. Then, `Math.floor()`

method rounds that number down to an integer:

## Properties for Constants

Math object properties are used for **math constants**. You are probably familiar with some of them, like the Pi number, or Euler's number. In cases when you need them in your JavaScript code, you might use the properties listed in the tables below. You will find both names of the constant and approximate values defined for each one.

Property | Description |
---|---|

E | Return Euler's number (approximately 2.718) |

LN2 | Return natural logarithm of 2 (approximately 0.693) |

LN10 | Return natural logarithm of 10 (approximately 2.302) |

LOG2E | Return base-2 logarithm of E (approximately 1.442) |

LOG10E | Return base-10 logarithm of E (approximately 0.434) |

PI | Return PI (approximately 3.1416) |

SQRT1_2 | Return square root of 1/2 (approximately 0.707) |

SQRT2 | Return square root of 2 (approximately 1.414) |

## Methods To Use

You can use various methods for working with math objects, too. They will let you get arithmetic as well as trigonometric values. See the table below to get familiarized with them. As you learn to use these methods, working with math objects will be a breeze.

Method | Description |
---|---|

abs(var1) | Return absolute value of var1 |

acos(var1) | Return arccosine of var1 in radians |

asin(var1) | Return arcsine of var1 in radians |

atan(var1) | Return arctangent of var1 as numeric value between -PI/2 and PI/2 radians |

atan2(var2,var1) | Return arctangent of the quotient of arguments |

ceil(var1) | Return var1 rounded upwards to nearest integer |

cos(var1) | Return cosine of var1 (var1 is in radians) |

exp(var1) | Return value of E^{var1} |

floor(var1) | Return var1 rounded downwards to nearest integer |

log(var1) | Return natural logarithm (base E) of var1 |

max(var1,var2,var3,...,n) | Return number with highest value |

min(var1,var2,var3,...,n) | Return number with lowest value |

pow(var1,var2) | Return value of var1 to power of var2 |

random() | Return random number between 0 and 1 |

round(var1) | Round var1 to nearest integer |

sin(var1) | Return sine of var1 (var1 is in radians) |

sqrt(var1) | Return square root of var1 |

tan(var1) | Return tangent of angle |
