Hi

I have been looking how to add a decimal into a string of text however none of the options are doing what I need it to so hoping someone can help out with a formula that I can use.

I have a dataset which I need to take and add a decimal place two from the end.

E.g

9999999999999 would become 99999999999.99
999999999990 would become 9999999999.90

And so on.

Any help would be greatly appreciated
