datatype英语字典
Datatypes are the classification of data that computers understand and can manipulate. They're like labels for different kinds of information. For instance, you might have a datatype for numbers, another for text, and yet another for images.
Numbers are one of the most basic datatypes. They're used to represent quantities and measurements. Integers, like 1, 2, 3, and so on, are whole numbers without
fractions or decimals. But computers also handle fractions and decimals, which are called floating-point numbers.
Text, or strings, is another common datatype. It's a sequence of characters that represents words, sentences, and paragraphs. Computers store text as a series of numbers that correspond to each letter, number, or symbol in a specific character set.
Images are a more complex datatype. They're made up of
pixels, which are tiny dots of color that, when combined, create the overall picture. Computers represent images using arrays of numbers that describe the color and intensity of each pixel.
Booleans are a simple datatype that represents only two possible values: true or false. They're often used in programming to make decisions or control the flow of a program.
Arrays and lists are datatypes that can hold multiple values of the same type. They're like containers that let you group related data together. Arrays are fixed in size.。
