description	In this tutorial, we will learn about the Math object in JavaScript. We will learn about the properties and methods of the Math object.

In JavaScript, the Math object is a built-in object that has properties and methods for mathematical constants and functions. It allows you to perform mathematical tasks on numbers.

Properties

The Math object has the following properties:

• Math.E: Returns Euler's number, the base of natural logarithms, approximately 2.718.

  for example:

  console.log(Math.E); // 2.718281828459045

• Math.PI: Returns the ratio of the circumference of a circle to its diameter, approximately 3.14159. for example:

      console.log(Math.PI); // 3.141592653589793

• Math.LN2: Returns the natural logarithm of 2, approximately 0.693. for example:

  console.log(Math.LN2); // 0.6931471805599453

• Math.LN10: Returns the natural logarithm of 10, approximately 2.303. for example:

  console.log(Math.LN10); // 2.302585092994046

• Math.LOG2E: Returns the base 2 logarithm of E, approximately 1.442.

  for example:

  console.log(Math.LOG2E); // 1.4426950408889634

• Math.LOG10E: Returns the base 10 logarithm of E, approximately 0.434.

  for example:

  console.log(Math.LOG10E); // 0.4342944819032518

• Math.SQRT1_2: Returns the square root of 1/2, approximately 0.707.

  for example:

  console.log(Math.SQRT1_2); // 0.7071067811865476

• Math.SQRT2: Returns the square root of 2, approximately 1.414.

  for example:

  console.log(Math.SQRT2); // 1.4142135623730951

Methods

The Math object has the following methods:

• Math.abs(x): Returns the absolute value of a number.

  for example:

  console.log(Math.abs(-5)); // 5
  console.log(Math.abs(5)); // 5

• Math.ceil(x): Returns the smallest integer greater than or equal to a number.

  for example:

  console.log(Math.ceil(5.1)); // 6
  console.log(Math.ceil(5.9)); // 6

• Math.floor(x): Returns the largest integer less than or equal to a number.

  for example:

  console.log(Math.floor(5.1)); // 5
  console.log(Math.floor(5.9)); // 5

• Math.round(x): Returns the value of a number rounded to the nearest integer.

  for example:

  console.log(Math.round(5.1)); // 5
  console.log(Math.round(5.9)); // 6

• Math.max(x, y, z, ..., n): Returns the largest of zero or more numbers.

  for example:

  console.log(Math.max(5, 10, 15, 20)); // 20

• Math.min(x, y, z, ..., n): Returns the smallest of zero or more numbers.

  for example:

  console.log(Math.min(5, 10, 15, 20)); // 5

• Math.pow(x, y): Returns the value of x to the power of y.

  for example:

  console.log(Math.pow(2, 3)); // 8

• Math.sqrt(x): Returns the square root of a number.

  for example:

  console.log(Math.sqrt(16)); // 4

• Math.random(): Returns a random number between 0 (inclusive), and 1 (exclusive).

  for example:

  console.log(Math.random()); // 0.123456789

• Math.sin(x): Returns the sine of a number.

  for example:

  console.log(Math.sin(90)); // 0.8939966636005579

• Math.cos(x): Returns the cosine of a number.

  for example:

  console.log(Math.cos(0)); // 1

• Math.tan(x): Returns the tangent of a number.

  for example:

  console.log(Math.tan(45)); // 1.6197751905438615

• Math.log(x): Returns the natural logarithm (base E) of a number.

  for example:

  console.log(Math.log(2)); // 0.6931471805599453

• Math.exp(x): Returns the value of E^x.

  for example:

  console.log(Math.exp(2)); // 7.3890560989306495

• Math.atan(x): Returns the arctangent of a number.

  for example:

  console.log(Math.atan(1)); // 0.7853981633974483

• Math.acos(x): Returns the arccosine of a number.

  for example:

  console.log(Math.acos(0)); // 1.5707963267948966

• Math.asin(x): Returns the arcsine of a number.

  for example:

  console.log(Math.asin(1)); // 1.5707963267948966

• Math.atan2(y, x): Returns the arctangent of the quotient of its arguments.

  for example:

  console.log(Math.atan2(1, 1)); // 0.7853981633974483

• Math.cosh(x): Returns the hyperbolic cosine of a number.

  for example:

  console.log(Math.cosh(0)); // 1
