Numbers are a fundamental data type in programming. They allow us to perform mathematical operations, store quantities, and represent values in various contexts.
In HTML, numbers are represented by the number data type.
Introduction to Numbers
In programming, numbers can be classified into two main categories: integers and floating-point numbers. Integers are whole numbers without a decimal point, while floating-point numbers (also known as floats) include decimal fractions.
Integers are positive or negative whole numbers or zero. They can be represented using the number data type in HTML.
For example, the number 5 is an integer.
Floating-point numbers include decimal fractions and exponential notation. They are often used to represent values that require more precision than integers can provide.
Floating-point numbers can also be represented using the number data type in HTML. For example, 3.14 is a floating-point number.
widthattribute of an HTML element specifies its width in pixels.
font-sizeCSS property sets the size of text in pixels.
let sum = 5 + 10;
let difference = 20 - 7;
let product = 3 * 4;
let quotient = 15 / 3;
