Fixed decimal point
It is possible to specify the number of digits of the fractional part of
a number to display. To use this function, press [2nd] (Fix) n, where n
is a number between 0 and 6. The calculator displays the number of
decimal places corresponding to the specified number, rounding the number
if necessary. Only the displayed number is rounded, not the internally
stored number.
To return to floating decimal point format, press [2nd] (Fix) [.] or turn
the calculator o

Rounding and precision
Each calculation generates an 11-digit result, even if the displayed
result is rounded to 10 digits (in standard notation) or 8 digits of
mantissa and two digits of exponent in scientific notation.
Transcendental mathematical functions require iterative processing. In
most cases, the cumulative error resulting from these operations exists
beyond the 10 displayed digits. Most calculations are accurate to within
± 1 unit of the last displayed digit.
