You can use InputForm to see that it really knows all digits (and will use them for any further calculation): ToExpression["109266.75"]//InputForm You could also change the "Displayed precision" from Edit -> Preferences in the Apearance -> Numbers -> Formatting tab. Other than that, there isn't anything to solve really :-) hth, albert
