Hi all!

Is it possible to insert a period into the middle of a string of numbers? I have 4315 numbers I need to change in F2 to F4316. Some of the number series have 3 digits, others have 4 or even 5 digits, but I always want to put the period after the 3rd digit.


For example:
I need to change 56812 to 568.12
or
7791 to 779.1

Thank you!
