You can change the PrintPrecision to larger value

--------------------------------------------------
SetOptions[$FrontEndSession,PrintPrecision->15]
ToExpression["109266.75"]

      109266.75
------------------------------------------------

To make it permanent, search your advanced
preferences (Options Inspector) for PrintPrecision
and change it there from the default 6 to any other value.
