What is the smallest ASCII value?
The smallest ASCII value is the null character, which corresponds to the binary 00000000. ASCII uses seven binary digits to represent all upper- and lower-case letters, the numbers 0 through 9, punctuation marks, and special control characters used in American English. 0 through 31 and 127, a total of 33, are control characters or communication-specific characters.
32 to 126, a total of 95 are characters, of which 48 to 57 for 0 to 9 ten Arabic numerals. 65 to 90 for the 26 upper case English letters, 97 to 122 for the 26 lower case English letters, and the rest for some punctuation, arithmetic symbols, and so on.
The last 128 are called Extended ASCII. Many x86-based systems support the use of Extended ASCII. Extended ASCII allows the eighth bit of each character to be used to determine an additional 128 special symbol characters, foreign language letters, and graphic symbols.
Extended information:
In standard ASCII, its highest bit (b7) is used as the parity bit. Parity is a method used to check for errors during code transmission, and is generally divided into two types: odd and even parity.
Odd parity is defined as the number of 1’s in a byte of the correct code must be odd, if it is not odd, then add 1 to the highest bit b7; even parity is defined as the number of 1’s in a byte of the correct code must be even, if it is not even, then add 1 to the highest bit b7.
Which one has the smallest ASCII value?
The lowercase letter with the smallest ASCII value is a.
What is the minimum value of ASCII code
The minimum value of ASCII code is 48.
The values of ASCII code are as follows:
48 to 57 are the ten Arabic numerals from 0 to 9;
65 to 90 are the 26 uppercase letters of the English alphabet;
Number 97 to 122 are the 26 lowercase letters of the English alphabet.
ASCII is a code that represents a character with a 7-bit binary number, which ranges from 0000000B to 1111111B, with 128 different code values.
