Base conversions (2, 10, 16)
This tool converts an integer between base 2, base 10 and base 16, showing each time the correct method for the chosen pair of bases: positional expansion (towards base 10), successive division by the target base (from base 10), or 4-bit grouping for direct conversion between base 2 and base 16. In every case the coefficients that multiply the powers of the base are highlighted, to make the link between the digits of the starting number and the calculation that uses them immediately clear.
