NX12 Measurement, Decimal Accuracy with copy to clipboard

When I do a measurement, NX 12 For example I get .12.  So I right click on this number and copy to the clipboard.  Then I paste into Excel.  The number is .120000000000

But the Actual Measurement is .124566545.  Why does .12 get pasted to the clipboard vs the actual real value to 6 or 8 decimal places.

I know I can change how the Measurement command displays number of decimal places.  But in older drawings that we have, this could cause some issues.

Thoughts on this>?

Thanks
