What is Bit Fiddle? Bit Fiddle is a compact app that helps users convert large decimal, hexadecimal or binary numbers or ASCII characters. It can compute the 1's complement or the 2's complement, alter the byte order of the input to convert between Little and Big Endian, and view a simple ASCII table with additional information for each character. The conversion results are displayed in different numeral systems and with the most common integer sizes: 8, 16, 32, 64 and n bits.
1. - ASCII characters: The input encoding is UTF-8 but only the printable characters of 7-bit ASCII are visible in the output.
2. - Convert artibtrary large decimal, hexadecimal or binary numbers or ASCII characters.
3. The endianness conversion automatically swaps the bytes of any input and will produce output based on that converted number.
4. You can enter any integer number formatted in any way you like: All characters not part of an integer will automatically be omitted.
5. The conversion results are displayed in different numeral systems and with the most common integer sizes: 8, 16, 32, 64 and n bits.
6. The n-variant uses as many bytes needed to store the unsigned representation of the entered number.
7. - View a simple ASCII table with additional information for each character.
8. - Alter the byte order of the input to convert between Little and Big Endian.
9. Note that converting very, very, very large numbers will take a considerable amount of time.
10. All in a compact interface which immediately shows you all needed values just one click or keystroke away.
11. All other characters are presented as a question mark.
