Math

Javascript Math

In JavaScript, Math is a built-in object. It has both properties and methods for mathematical functions and constants.

Math operates with the Number type, but never with BigInt.

Unlike other global objects, Math is not considered a constructor. The methods and properties of Math are fixed. You can call them by applying Math as an object without creating it.

So, you refer to constant pi as Math.PI. Hence, the sine function should be called Math.sin(x). Here, x is the argument of the method.

The syntax to call the methods and properties of Math is the following:

var pi_value = Math.PI;
var sin_value = Math.sin(30);

Properties of Math

Now let’s check out the list of math properties with their descriptions.

Math.LN2

The natural logarithm of 2: nearly 0.693.

console.log(Math.LN2);

Math.LN10

The natural logarithm of 10; nearly 2.303.

console.log(Math.LN10);

Math.LOG2E

E’s base 2 logarithm; nearly 1.443.

console.log(Math.LOG2E);

Math.LOG10E

E’s base 10 logarithm; nearly 0.434.

console.log(Math.LOG10E);

Math.PI

The circumference ratio of a circle to its diameter ,nearly 3.14159.

console.log(Math.PI);

Math.SQRT1_2

½ square root ( or correspondingly 1/√2); nearly 0.707.

console.log(Math.SQRT1_2);

Math.SQRT2

The square root of 2; nearly 1.414.

console.log(Math.SQRT2);

The Methods of Math

Below you will find the list of the math methods and their descriptions;

Math.abs(number)

This method is targeted at returning the absolute value of a number.

console.log(Math.abs(-10)); 
console.log(Math.abs('-10'));
console.log(Math.abs(-20 * 2));

Math.acos(number)

Returning the arccosine (in radians) of a number.

console.log(Math.acos(0.75)); 
console.log(Math.acos(-0.9)); 
console.log(Math.acos(3));

Math.acosh(number)

Returning the hyperbolic arccosine of a number.

console.log(Math.acosh(1)); 
console.log(Math.acosh(1.5)); 
console.log(Math.acosh(0.99));

Math.asin(number)

Returning the arcsine of a number.

console.log(Math.asin(0.75)); 
console.log(Math.asin(-0.9)); 
console.log(Math.asin(2));

Math.asinh(x)

Returning the hyperbolic arcsine of a number.

console.log(Math.asinh(1)); 
console.log(Math.asinh(1.5)); 
console.log(Math.asinh(-2));

Math.atan(x)

Returning the arctangent of a number.

console.log(Math.atan(0.75)); 
console.log(Math.atan(-0.9)); 
console.log(Math.atan(2));

Math.floor(x)

Returning the largest integer that is less than or equal to a number.

console.log(Math.floor(2.65));
console.log(Math.floor(7.1)); 
console.log(Math.floor(5.8));

Math.pow(x, y)

Returns the exponent power base, which is xy.

console.log(Math.pow(3, 3)); 
console.log(Math.pow(4, 2)); 
console.log(Math.pow(2, 5));

Math.round(x)

Returning a number’s value rounded to the nearest integer.

console.log(Math.round(32.65));
console.log(Math.round(7.4)); 
console.log(Math.round(6.1));

Math.sin(x)

Returning a number’s sine.

console.log(Math.sin(2)); 
console.log(Math.sin(0)); 
console.log(Math.sin(-1));

Math.sqrt(x)

Returning the positive square root of a number.

console.log(Math.sqrt(81)); 
console.log(Math.sqrt(16)); 
console.log(Math.sqrt(-4));
