What are half-width English numbers?

Question 1: What is a half-width English number? What do you mean? In order to answer your question, you must first understand what a half angle is and what a full angle is (although all you want to know is how to input numbers with a half angle). 1. Half-angle, also called half-angle, is a format of computer characters. Literally, it is only half the width of a full-width character. Chinese, Japanese and Korean characters are stored in two bytes, which occupy a wider width on the screen than Latin letters or numbers. Therefore, Chinese, Japanese and Korean characters are called full-width characters, and Latin letters or numbers are called half-width characters. In JIS X 020 1 coding table, it puts Japanese katakana in a byte space, so they are also called "half-width katakana". And full width, also known as full width, is a format of computer characters. Literally refers to characters that are wider than ordinary characters (or half-width characters). Traditionally, in computer systems used in English or Latin alphabet languages, each letter or symbol is stored in a byte space (a byte has 8 bits and ***256 coding spaces); Chinese, Japanese and Korean characters usually use two bytes to store one character, because the number is far more than 256. Because Chinese, Japanese, Korean and other characters will be stored and displayed in two bytes, where fixed-width characters are used (such as DOS, some text editors, etc. ), in order to make the font look neat, English letters, numbers and other symbols have also changed from occupying only one word space to occupying two words space for display, and stored in two bytes. Okay, a bunch of crap. In fact, it is very simple to switch half/full angle input under the windos interface. Generally, the default key combination is shift+ space only when Chinese/Japanese/Korean input is turned on. Take the intelligent ABC input method as an example. When the small picture behind the standard is a black crescent, it is in a half-angle input state. If it is a black circle, it is a full-angle input state. Now let's show you the half angle of the effect: 1 2 3 4 5 6 7 8 9 0. Full-width number: 1 2 3 4 5 6 7 8 9 ... Because of the format of the page, the effect I am showing you now is a little different from the reality. You can try it on the text yourself.

Simply put, it is to use shift+space.

Question 2: How to input half-width English numbers? .

Question 3: What are half-width English numbers? Unless it is opened in the input method, it is half-angle.

In the input method, there is a button, which is, or. The former is half angle and the latter is full angle.

Question 4: What's the difference between English and Chinese? What's the difference between typing numbers? It doesn't matter whether you can enter them or not. Sometimes the whole picture can't get in. Or in a document, the difference between numbers and letters of half-angle matching and full-angle matching is obvious.

Question 5: What are the half-width English numbers? N represents the number entered in the case of half angle. Half-width occupies the position of 1 character, and full-width occupies the position of two characters.

Question 6: How to enter numbers in English half-angle? Switch to the English input method first, and then there is a full-width and half-width switch on the status bar of the input method. The crescent pattern is half-width and the circular pattern is full-width.

Take sogou input method as an example:

Point shift is changed to English input, which is generally the default half-angle state. These numbers and symbols are

1234567890,.！ ?

Click the crescent pattern with the mouse or shift+ Spacebar to switch to full-width numbers and symbols.

1234567890.,! ?

We can see that the numbers and symbols in full-angle state are fatter and the distance is larger, because full-angle accounts for 2 bytes and half-angle accounts for 1 byte.
