insert decimal

Hi Experts,

I have variable var1 and I want to insert a decimal at 5 places to the left from the last digit(unit digit) and do calculations on that. How to do that?

Say for example,

var1 = 60000567

I want the result to be 600.00567 and then do calculations with this variable.

Please let me know how to code for it.

Thanks in advance,

Sangeeta.
