Thanks Mr.777, I'm affraid I didn't really understand you explanation! :confused: I actually have no need or intention to create variables at run time. As you say there are plenty of alternative...

Thanks for that. I went off on a bit of a tangent and after extensive experimenting (and before checking back here to find your answer) i tried several alternative solutions. Turns out I can't create...

How would I go about re-assigning a value to an immutable object? Would I have to create a new BigInteger for every time the loop is excecuted?

Thanks I'll try that next.

First its getting late and I should probably call it a day but I'm still fighting this BigDecimal issue... I can't use long for the 100! so I have had tio move to...

On the topic of BigDecimal. How would you go about computing a number that exceeds the memory limit of the computer?

I'm trying to calculate 100! (ie. 100 x 99 x 98 x 97 .... 3 x 2 x 1), but this...

Ok so I'm basically olong the right tracks, I havn't missed any easy solution. Thanks very much.

I'm working on two seperate problems both using BigDecimal. One of them is simply to calculate the product of the digits that make up 2 to the power of 1000. I've successfully done this but I was...

Ok, I have a number that is 1000 digits long. its too big to be of type long so I have had to make it a BigDecimal. Lets say for example that the number starts:

9837425678934653.........

Sorry: I need to work with the individual values as int so if possible I'm trying to avoid going from BigDecimal > String (or char[] etc.) > int.

Assuming that I have a BigDecimal. What would be the best apprach to breaking that down into indivual digits so I can utilise the individual values. I know there are several ways this can be done but...
