    Fractional calculations can display fractional or decimal
    results. Results are automatically simplified.
    ¦ N
    enters a fraction. Press
    N
    between whole number,
    numerator, and denominator. The unit, numerator, and
    denominator must be positive integers.
    ¦ %
    j
    converts between fractions and decimals.
    ¦ %
    O
    converts between mixed numbers and
    simple fractions.

    Angle Modes
    I
    =
    I
    displays a menu to specify the Angle mode as
    degrees, radians, or gradients.
    =
    displays a menu to specify the Angle unit modifier—
    degrees (

    ), radians (
    r
    ), gradients (
    g
    ), or DMS (
    Ä
    Å
    Æ
    ). It
    also lets you convert an angle to DMS Notation (
    4
    DMS
    ).
    To set the Angle mode for any part of an entry:
    ¦
    Select the Angle mode. Entries are interpreted and results
    displayed according to the Angle mode, or
    ¦
    Select a unit modifier (
    Ä
    Å
    Æ
    ) for any part of an entry.
    Entries with unit modifiers are interpreted accordingly,
    overriding the Angle mode.
    To convert an entry:
    ¦
    Set the Angle mode to the unit you want to convert to.
    Then use a unit modifier to designate the unit to convert
    from. (Angles of trigonometric functions convert values
    inside parentheses first.), or
