Hi Tigger1725, I'm having the same problem. I'm setting variables, most with decimal places, then when I set the captured value to a field the numbers have been rounded down to full numbers no decimals. Really annoying. Please let me know if you have come across the solution.
My issue ended up being created by a different problem and was answered on another thread!
I would start a new thread with your question because I would not be the most qualified person to answer.
