Hello, Amazing learners!

Today, we learnt about some Math modules which help in felicitating mathematical operations. Also we built a Random Number Generator

Math Module

1. Math.PI

PI - This method returns the value of PI

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

2. Math.max() & Math.min()

max & min - This methods returns max or min number from the list of the numbers provided respectively

console.log(Math.max(1,2,3,4,5,6,7,8,9)) // logs 9
console.log(Math.min(1,2,3,4,5,6,7,8,9)) // logs 1

3. Math.pow(x,y)

pow - This method returns the exponential of a number

console.log(Math.pow(2, 3)) // logs 8 which is equal to 2^3 // pow(x,y) returns x^y

4. Math.round(x)

round - This method returns the rounded number

console.log(Math.round(10.999)) // logs 11 // rounds to nearest integer

5. Math.abs(x)

abs - This method reurns the absolute value/mod of a number

console.log(Math.abs(-10.52569)) // logs 10.52569 // abs returns the positive counterpart of the number

6. Math.trunc(x)

Trunc - This method returns the integral part of the number

console.log(Math.trunc(6.524)) // logs 6 // returns only the integral part of the number
                               // if a.bcd is a number, this will return a

7. Math.random()

Random - This method reurns a random number between 0 to 1

console.log(Math.random()) // returns a random number between 0 to 1

A special formula to generate random number in a range

const max=8
const min=5
console.log(Math.floor(Math.random() * (max-min + 1))+ min)

8.Math.floor(x)

Floor Function - A function which returns biggest integer smaller than the number.

console.log(Math.floor(10.528)) // logs 10
cosnole.log(Math.floor(-10.528)) // logs -11

9. Math.ceil(x)

Ceiling Function - A function which returns smallest integer bigger than the number.

console.log(Math.ceil(10.528)) // logs 11
console.log(Math.ceil(-10.528)) // logs -10
