8.2.3 Setting the Calculation Precision.
The maximum number of decimal places that are displayed can be set from 0 to 9. This is done by
pressing:
Nemeth: SPACE with dots 4-6.
UK Braille: SPACE with dot 2.
UEB: SPACE with dots 2-5-6.
followed by the desired number of digits. This does not affect the internal precision of calculations,
but only the number of digits that are displayed.
For example, to set the number of decimal places to 4, enter the calculation precision command, as
listed above.
KeyPlus prompts: "Decimal places currently (current setting)."
Type 4 and press ENTER. If you are checking the precision, just press ENTER to leave the current
setting unchanged.
