HP
An acronym for Hewlett-Packard, another respected vendor of fine graphing calculators.
implied multiplication
A convention used by the TI-89 / TI-92 Plus CAS which allows omission of the multiplication operator in
some expressions. For example, 2x is equivalent to 2*x. However a(x) is not interpreted as a*x, but
instead as calling function a() with an argument of x. Also, the expression 2ab is not interpreted as
2*a*b, but instead as 2*ab, where ab is a single variable.
integer
A number with no fractional component. -1, 0 and 42 are integers; -1.1 and 2/3 are not integers. See
also floating-point.
interpolation
Estimating the value of a function between two known values.
k or K
Abbreviation for 1024. 1K bytes is 1024 bytes.
kernel
Software which gives assembly programs access to calculator machine resources. Assembly
programs which are not no-stub require a kernel. See also shell.
keyboard shortcut
A key press combination to perform a calculator function. The keyboard shortcuts are listed in the
TI-89/TI-92 Plus Guidebook.
LCD
An acronym for liquid-crystal display. The displays used on the TI-89 / TI-92 Plus are LCDs.
LCD connector; LCD port
The unlabeled rectangular connector on the back of the TI-92 Plus which is used to connect an LCD
display screen for overhead projection. Actually called the ViewScreen port. The TI-89 does not have
this connector. See also ViewScreen.
LSD; LSB See most significant digit
least significant digit; least significant bit See most significant digit
library
A calculator file containing ASM utility programs which are used by other programs. Libraries save
memory when several calculator programs need the same utilities, since the library eliminates
duplicating the utilities in each program. Libraries can cause problems if programmers do not ensure
that the library version is compatible with the program version, or the library is not located in the correct
folder.
linear format
The opposite of 'Pretty print': a representation of an expression such that all the symbols and operators
are on one line. Expressions are shown in linear format in the entry line. The expression
(a^b+b^)^(1/3) is in linear format.
