SHOWing Full 12–Digit Precision
Changing the number of displayed decimal places affects what you see, but it does
not affect the internal representation of numbers. Any number stored internally
always has 12 digits.
For example, in the number 14.8745632019, you see only "14.8746" when the
display mode is set to FIX 4, but the last six digits ("632019") are present internally
in the calculator.
To temporarily display a number in full precision, press

you the mantissa (but no exponent) of the number for as long as you hold down
