Math Object in Java Script

 Math : 

Math object helps us to perform a mathematical operation 

// console.log(Math.PI);

//-----------------------------------

// console.log(Math.round(3.53273));

//--------------------------------------

// console.log(Math.pow(4.2,8));

// console.log( Math.round(Math.pow(4.2,8)));

//--------------------------------------

// console.log( Math.sqrt(16));

//--------------------------------------

// console.log( Math.abs(-16)); //return positive value always

// //--------------------------------------

// console.log( Math.ceil(99.1));   // alawys increment

// console.log( Math.round(99.41)); 

// //--------------------------------------

// console.log( Math.floor(99.61));  //remains same

// console.log( Math.round(99.41)); 

// //--------------------------------------

// console.log(Math.min(0,60,37,-34,43));

// console.log(Math.max(0,60,37,-34,43));

//--------------------------------------

// console.log(Math.round(Math.random()*5));

// console.log(Math.floor(Math.random()*5));

//--------------------------------------

// console.log(Math.trunc(4.5)) //return integer part of the number

// console.log(Math.trunc(-4.8)) //return integer part of the number

// practice time 

let a = 8.9

console.log(Math.trunc(a));

console.log(Math.floor(a));

console.log(Math.ceil(a));
