Accuracy Information
The calculator stores results internally as 13-digit numbers but displays them
rounded to 10 digits or fewer, depending on the decimal format. The internal
digits, or guard digits, increase the calculator’s accuracy. Additional
calculations use the internal value, not the value displayed.
Rounding
If a calculation produces a result with 11-digits or more, the calculator uses the
internal guard digits to determine how to display the result. If the eleventh digit
of the result is 5 or greater, the calculator rounds the result to the next larger
value for display.
For example, consider this problem.
1 P 3 Q 3 = ?
Internally, the calculator solves the problem in two steps, as shown below.
1. 1 P 3 = 0.3333333333333
