Set of three simple modules that visually describe the process of coding binary numbers for the following formats:

Natural binary (complementa.exe app)
One’s complement for negatives (complementa.exe app)
Two’s complement for negatives (complementa.exe app)
Parity bit (complementa.exe app, by using the tooltip over any binary string)
IEEE754 format of floating point numbers (IEEE754.exe app)

The comaflotante.exe app visualizes the concept of “floating the decimal point” accross the mantissa, and the relationship it has with the base (decimal poin floats an integer number of steps when it’s represented using the same base or any multiple of it)
