JavaScript Math obyekti raqamlar ustida matematik vazifalarni bajarishga imkon beradi va boshqa obyektlardan farq qilgan holda matematik obyektda konstruktor yo’q shuningdek matematik obyekt statik.!
Har qanday matematik xususiyat sintaksisi Math.property ko’rinishida bo’ladi.!
JavaScript Matematik xususiyatlari sifatida foydalanish mumkin bo’lgan 8 ta matematik konstantalarni taqdim etadi:
Math.E // Eyler raqamini qaytaradi.!
Math.PI // PIni qaytaradi.!
Math.SQRT2 // 2 ning kvadrat ildizini qaytaradi.!
Math.SQRT1_2 // 1/2 kvadrat ildizini qaytaradi.!
Math.LN2 // 2 ning natural logarifmini qaytaradi.!
Math.LN10 // 10 ning natural logarifmini qaytaradi.!
Math.LOG2E // E ning 2 ta logarifmini qaytaradi.!
Math.LOG10E //E ning 10 ta logarifmini qaytaradi.!
1.
let mathem=Math.E;
console.log(mathem);
//natija - 2.718281828459045
2.
let mathem=Math.PI;
console.log(mathem);
//natija - 3.141592653589793
3.
let mathem=Math.SQRT2;
console.log(mathem);
//natija - 1.4142135623730951
4.
let mathem=Math.SQRT1_2;
console.log(mathem);
//natija - 0.7071067811865476
5.
let mathem=Math.LN2;
console.log(mathem);
//natija - 0.6931471805599453
6.
let mathem=Math.LN10;
console.log(mathem);
//natija - 2.302585092994046
7.
let mathem=Math.LOG2E;
console.log(mathem);
//natija - 1.4426950408889634
8.
let mathem=Math.LOG10E;
console.log(mathem);
//natija 0.4342944819032518
JavaScriptda sonlarni butun songa yaxlitlashning 4 ta umumiy usuli mavjud.!
1.Math.round(x) – kiritilgan raqamni haqqoniy yaxlitlaydi.!
let result1=Math.round(12.1);
console.log(result1);
//natija - 12
let result2=Math.round(12.5);
console.log(result2);
//natija - 13
let result3=Math.round(12.9);
console.log(result3);
//natija - 13
2.Math.ciel(x)– kiritilgan raqamni katta tomonga yaxlitlaydi.!
let result1=Math.ceil(12.001);
console.log(result1);
//natija - 13
let result2=Math.ceil(12.5);
console.log(result2);
//natija - 13
let result3=Math.ceil(12.9);
console.log(result3);
//natija - 13
-
Math.floor(x)– kiritilgan raqamni kichik tomonga yaxlitlaydi.!
let result1=Math.floor(12.001);
console.log(result1);
//natija - 12
let result2=Math.floor(12.5);
console.log(result2);
//natija - 12
let result3=Math.floor(12.9);
console.log(result3);
//natija - 12
-
Math.trunc(x)– kiritilgan raqamni butun qismini qaytaradi.!
let result1=Math.trunc(0.9);
console.log(result1);
//natija - 0
let result2=Math.trunc(-12.5);
console.log(result2);
//natija - (-12)
let result3=Math.trunc(12.9);
console.log(result3);
//natija - 12
Math.sign(x)–
let result1=Math.sign(12.12);
console.log(result1);
//natija - 1
let result2=Math.sign(0);
console.log(result2);
//natija - 0
let result3=Math.sign(-9.4);
console.log(result3);
//natija - (-1)
Math.pow(x,y) –
let result1=Math.pow(3,4);
console.log(result1);
//natija - 81
let result2=Math.pow(25,2);
console.log(result2);
//natija - 625
Math.sqrt(x)–
let result1=Math.sqrt(25);
console.log(result1);
//natija - 5
let result2=Math.sqrt(1200);
console.log(result2);
//natija - 34.64101615137755
Math.abs(x)–
let result1=Math.abs(-2);
console.log(result1);
//natija - 2
let result2=Math.abs(2);
console.log(result2);
//natija - 2
