What is the ASCII Code of ½?
ascii, iso-8859-1, unix, windows
Solution
½ is not a character in the ASCII character set.
The values you're finding online probably differ because they're using different character sets. For example, before Unicode was invented, localized versions of Windows all used different code pages, in which the basic ASCII set was extended with some additional characters.
Now, of course, everything is (or should be) fully Unicode. Detailed Unicode information for that character (vulgar fraction one half) can be found here. Note that there are also multiple representations for the same numerical value (e.g., base 10, hex, binary, etc.).
Problem
I want to print the value '½' in a file. I searched for the ascii value of this as Alt+(ascii Value) will give you the same. To my surprise I found 2 ascii values for this symbol in various sites. One is 171 and the other is 189. I tried to write this symbol by using 171 and 189. Again to my surprise, if I am writing in Windows, 171 will give me this symbol. But if I am writing in UNIX, 189 will give me this symbol. I was aware that there cant be 2 ASCII Values for a same symbol. But I got 2 valid codes for the same symbol in different OS. So can anyone tell what is the real ASCII Code for the symbol ½ ??
