What is the difference between half-angle and full-angle
Full-angle: refers to the state in which a character occupies two standard character positions. Chinese characters and English characters that specify full-width, as well as graphic symbols and special characters in GB2312-80 are all full-width characters.
Half-angle: i.e., a character occupies the position of one standard character.
The difference between the two is as follows:
What is the difference between a full corner and a half corner?
I. Differences in nature
1. Full corner: a character occupies the state of two standard character positions.
2. Half corner: a character occupies one standard character position.
Two, the use of different
1, full-width: letters and numbers, etc. and Chinese characters occupy the same width position.
2, half-corner: ASCII characters, in the absence of Chinese character input method to play a role in the input of alphanumeric and character are half-corner.
Three, representing different symbols
1, full angle: in GB2312-80 (“Information Exchange Chinese Character Code Character Set – Basic Set”) in a variety of symbols, such as A, B, C, 1, 2, 3, etc., should be understood as Chinese characters.
2. Half-corner: various symbols in the ASCII code of English documents, such as A, B, C, 1, 2, 3, etc..

In the daily use of computer systems, the initial input method is generally defaulted to the English input method. At this point, it will naturally be in a half-corner state. Whether you are typing letters, symbols or numbers, it always occupies only one English character position. If you switch to the Chinese input method state, there will be two options of full corner and half corner, for Chinese characters, these two options have no effect on them.
They always occupy two English character positions, but for symbols, numbers, and letters typed in this state, this is very important, as follows:
The former option selects half-corner, the The latter selects full corners. These two methods give completely different results. When full angle is selected, letters, symbols and numbers are considered as Chinese characters. From a visual point of view, they therefore also look much more awkward.
What’s the difference between a full corner and a half corner
When we’re typing using Typewriter, sometimes we have to type a punctuation mark. Obviously the keyboard shows the symbol but has not been able to type it, this is the keyboard accidentally cut to the full corner. Below I give you the difference between full-angle and half-angle, take a look together.
Difference between full-angle and half-angle
Full-angle and half-angle are mainly for punctuation, full-angle punctuation accounts for two bytes, half-angle accounts for one byte. Regardless of whether it is half- or full-corner, Chinese characters take up two bytes.
Introduction to full-width and half-width
1. Full-width: A computer character that is a full-width character occupying the place of two standard characters (or two half-width characters). A full-width character occupies two bytes.
Chinese characters and English characters specified in full-width and the national standard GB2312-80 graphic symbols and special characters are all full-width characters. In full-width, letters and numbers, etc. occupy the same equal width as Chinese characters.
2. Half-width: It means that a character occupies a standard character position. A half-corner occupies one byte.
Half-corner is the ASCII way of characters, when there is no Chinese character input method works, the input letters, numbers and characters are half-corner.
Each half-width character occupies only one byte of space (one byte has 8 bits, totaling 256 code spaces). Pictograph languages such as Chinese, Japanese, and Korean have much larger font sizes than 256 encoding spaces, so they are stored in two bytes instead. At the same time, because of the writing habits of CJK and other hieroglyphic languages, if you use full-width characters in a unified way, you can arrange them in a neat way.
For neatness, English and other Latin characters and punctuation are also provided in full-width format.
Using full and half-width characters
1. The shortcut for switching between full and half-width characters in the Chinese input method is SHIFT+space.
2. General system commands do not use full-width characters, but only in word processing.
3. You can only use half-width punctuation in the source code of a program, but you can use full-width characters or full-width punctuation for the data inside a string.
4. On computers that do not support languages such as Chinese characters, you can only use half-width punctuation. In fact, in this case there is no such thing as a full-width half-width concept.
5. In the Chinese character input method, alphanumeric input defaults to half-width, but punctuation defaults to full-width.
You can change the state of full-width and half-width by clicking the corresponding button on the toolbar of the input method. The buttons on the left of the input method name “Wubi Type” are for changing the Chinese and English inputs, the circles and semicircles on the right are for changing the full or half-angle of the letters and numbers, and then the right “. ,” or “. ,” is to change the punctuation in English and Chinese settings (Chinese punctuation that is full-width, English punctuation that is half-width), the rightmost keyboard icon is to display the soft keyboard, you can enter some special characters or other languages inside the letters.
What is the difference between half-angle and full-angle?
The differences between half-angle and full-angle are:
1. Different typing effects.
In the full-angle state, the first change is our space bar. Switch to the full corner state, press the space, we will find that the distance between the two characters becomes very large, this very large is compared with the half-corner state. The second change is the English letters, which are typed in the half-width state are smaller, that is, normal. Then switch to the full corner of the state, we can clearly see that the letters of the alphabet is bold and large.
2, different visual.
A half-angle symbol occupies a character, narrower; full-angle symbol occupies the position of two characters, wider.
3, storage is different.
A half-angle symbols account for a byte, a full-angle symbols account for two bytes, the difference in storage is the essence of this difference stems from the two encoding methods are different.
Generally in writing Chinese articles with full-width, write English articles with half-width, because the English accounted for a character. This looks comfortable. Half-angle full-angle is mainly for punctuation, full-angle punctuation accounted for two bytes, half-angle accounted for a byte, and regardless of half-angle or full-angle, Chinese characters are still to account for two bytes. You can only use half-width punctuation in the source code of a program, and you can only use half-width punctuation on computers that don’t support languages such as Chinese characters.
What is a full angle and what is a half angle?
I. The concepts of full corner and half corner.
Full corner: a state in which a character occupies two standard character positions.
Half-angle: the state in which a character occupies one standard character position.
2. Application of full corner and half corner.
1, in Chinese, the text of all the use of full-corner, that is, a text occupies two character positions.
2, Chinese Arabic numerals can be full-angle or half-angle. As follows:
3. The letters of the alphabet in English can be full-width. It can also be half-width.
3. Switching between full-angle and half-angle.
1, in the input method, there is a crescent-shaped pattern for the half-angle state, click it can be switched to full-angle.
2, in the input method, there is a round pattern for the state of full-angle, click it to switch to half-angle. The following picture:
What is the difference between a full corner and a half corner?
(1) Full-width – means that one character occupies two standard character positions.
Handwriting characters and English characters that specify full-width, as well as graphic symbols and special characters in GB2312-80, are all full-width characters. General system commands do not use full-width characters, only in word processing will use full-width characters.
(2) Half-width — means that a character occupies a standard character position.
The usual alphabet, numeric keys, and symbol keys are half-width, and half-width display internal codes are one byte. Within the system, the above three characters are treated as basic code, so users generally use half-width when entering commands and parameters.
