1. Object types and formats. This table shows the correct delimit-
ers and examples for the 10 basic types of object. An "object" is any of
the individual items you work with on the calculator. The 10 basic
object types are:
• Real numbers, such as 5 or -4.3
• Complex numbers, which are a pair of real numbers representing a
complex number x
or a point in a plane.
• Binary integers, which are unsigned integers used in computer
• Strings, which contain arbitrary sequences of characters.
• Vectors, which are one-dimensional arrays used in linear algebra.
• Matrices, which are two-dimensional arrays used in linear algebra.
• Lists, which contain arbitrary sequences of objects.
• Names, which enable you to name and store other objects and to
perform symbolic calculations.
• Programs, which enable you to create your own commands.
• Algebraics, which represent mathematical expressions and
2. Menu selection (shifted). Use the menu selection keys to assign
commands to the menu keys. For example, press
the ARRAY menu. To select a different menu, press another menu
There are additional menu selection keys on the right-hand keyboard
(see item 16).
3. Object delimiters. These symbols identify the different object
types (see item 1). For example,
identifies binary integers, while
Real numbers require no delimiters. Symbolic objects (names and
algebraics) require the
delimiter, located on the right-hand key-
board (see item 11).
4. Lowercase. Press
to key in lowercase letters. Lowercase
mode continues until you press
a second time, press
process the command line, or press
to clear the command line.
