Convert decimal numbers to binary, with hex and octal alongside.
Enter a valid decimal number (e.g. 42 or 3.75), integers of any size (or fractions up to ~15 digits of precision).
Fractional parts are converted with up to 24 binary places. Binary is position-2 notation: 1011 = 1·8 + 0·4 + 1·2 + 1·1 = 11.
