Thanks for everyones help. I now think what I am looking for is not really possible or at least not very easy. Many thanks everyone for putting me right, I won't waste anymore of your time.

Thanks for that StatusX. I get what you are saying. OK, so I have to be happy to make guesses and do things by poke a hope and iteration, but can you formula transpose for example, a geometric series, if you already have the result of x and give some of the terms needed. If for example...

Forgive me, but I don't understan the term "function of merit". I am not very good at maths. Lets use a silly example ... x = 97651234564312454398547234923469823476349329 Taking this relatively small number as an example Test 1 lets say that 123 ^ 47 = x - 52342341234 (I...

Thanks Werg22, that fasinating. Here is a bit more meat. If I choose to find a geometric progression, for example, that was close to the number needed. The only way I see is for me to jump in and calculated progressiivly larger and lager numbers and compared each one until I went bigger...

No, nothing special about it, it is however very very big, maybe millions of digits.

I want to approximate a very large number in a small way. I have looked at geometric progression (which I can just about understand), but it seems to only work forwards. I want to supply a very large number and come up with a formula that will represent an approxmation of that number. The...
