A Universal Decimal/Binary/Hex Converter v2.0

This code will convert any decimal, binary or hex number into the other two formats. A good code for those who want to learn how to use functions with multiple and optional parameters, also maths functions and creating a custom GUI. The program handles 8bit, 16bit, fixed-point, floating point and any length binary upto 31 bits. Full instructions given in the help window + extensively commented code. I'd appreciate some votes for this if you think it deserves them.
