Bitmeter is a utility for inspecting a bitfield and investigating how different data types are represented. Possible uses include contrasting and comparing the encodings of the different types used in languages like C and Java, converting values of one type to another, and debugging.The bitfield can be 1, 2, 4, or 8 bytes long. (For the larger bitfields, a hardware keyboard is useful, but not essential.) Depending on the number of bytes, the field is simultaneously shown as a signed integer, an unsigned integer, an ASCII character, a Unicode character, a float, and a double. It’s also shown in binary, decimal, and hexadecimal. The bitfield can be changed by toggling the bit buttons or typing in any of the type boxes. Additional buttons make it easy to turn all bits on or off, negate, and add or subtract 1.
