Entering List Elements
A named list accepts two types of elements: numerical and
text.
• Lists that contain numerical elements not enclosed in
quotation marks are called numerical lists.
• Lists that contain text elements or numerical elements
whose numerical values are ignored (because they are
enclosed in quotation marks) are called categorical lists.
To enter an element, highlight the space in the column under
the list name where you want the element to be entered (you
can’t skip any spaces) and type in the element (it is displayed
on the entry line). Press b or # to move the element into
the list. Pressing # or b also moves the cursor to the next
element space.
Access the quotation marks (for categorical lists) from the
Text editor (- t).
Numerical Lists
Numerical lists contain real numbers, fractions, or expressions
that evaluate to real numbers or fractions. If you enter an
expression like
sin(30)
, the calculator displays the decimal
equivalent in the list element space. The Numeric Notation,
Decimal Notation, and Angle modes determine how the
calculator displays all elements, except fractions.
Define ¨ NUM={18,25,45}
