Last Answer
When a calculation is completed by pressing 4, or a calculation is completed during
another operation, the result is stored in a memory location that contains the last calculated
result. This enables the last result of a calculation to be used during the next calculation.
To access the last calculated answer, press v4. Unlike the other stored memory
registers however, this register is automatically updated when you complete a calculation.

Display Format of Numbers
When you turn on the HP 10bII+ for the first time, numbers are displayed with two decimal
places and a period as the decimal point. The display format controls how many digits
appear in the display.
If the result of a calculation is a number containing more significant digits than can be
displayed in the current display format, the number is rounded to fit the current display setting.
