Decoding
Turn a number back into the letters that make it.
The number is split into thousands, hundreds, tens and units, and each part becomes the letter carrying that value. Add the letters back up and you return to your number.
Use it on a total you have already worked out here, not on an arbitrary number. The letters it returns are the raw material for the next step, and in the tradition they are then rearranged by the practitioner — which is judgement, not arithmetic, and not something this or any program can do for you.
