How to add a decimal to second to last digit

[griffin2571]

I am trying to add a decimal to the second to last digit on the parts order column. For example Parts Order  is

PARTS +0080 I am trying to convert to PARTS +008.0

How do I change the format for this?

Left([Parts Order],Len([Parts Order])-1)&'.'&Right([Parts Order],1)
