The fraction key ( ) cycles through three varieties of fractional display. If the current answer is the
decimal fraction 5.25, pressing converts the answer to the common fraction 21/4. If you press
again, the answer is converted to a mixed number (5 + 1/4). If pressed again, the display returns to
the decimal fraction (5.25).
The HP Prime will approximate fraction and mixed number representations in cases where it cannot nd exact
ones. For example, enter √5 to see the decimal approximation: 2.236…. Press
once to see and
again to see . Pressing a third time will cycle back to the original decimal representation.
Hexagesimal numbers
Any decimal result can be displayed in hexagesimal format; that is, in units subdivided into groups of 60. This
includes degrees, minutes, and seconds as well as hours, minutes, and seconds. For example, enter
to see
the decimal result: 1.375. Now press to see 1°22′30. Press again to return
to the decimal representation.
The HP Prime calculator will produce the best approximation in cases where an exact result is not possible.
Enter √5 to see the decimal approximation: 2.236… Press to see 2°14′9.84472 .
