• The fractional part
A numeral insertion is made to the left of the cursor. When numerals exist at all places, entering a
new numeral deletes the rightmost numeral of the fractional part.
Additionally, entering a numeral at the rightmost place of the fractional part overwrites the current
numeral.
Example: Insertion of "2" between "5" and "6" to show "1.526"
Example: Overwriting the rightmost numeral "7" to show "1.560"
Cursor movement
to the rightmost
numeral "7"
Deletion of numerals
The DELETE key deletes the numeral at the cursor.
• The whole number part
Example: Deletion of "1" from the whole number part of "1.234"
