By default machine precision number are displayed only with six digits, but the precision is still there. If you position the cursor on the output cell and press space, you'll see this. Also try FractionalPart@ToExpression["109266.75"] So don't worry, only the display is truncated for convenience (in your case inconvenience but most of the time it's better not to see all 15 or so digits all at once) -- Szabolcs Horvát Visit Mathematica.SE: http://mathematica.stackexchange.com/
