To maximize accuracy, the TI
.
83 carries more digits
internally than it displays. Values are stored in memory
using up to 14 digits with a two-digit exponent.
•
You can store a value in the window variables using up
to 10 digits (12 for
Xscl
,
Yscl
,
Tstep
, and
q
step
).
•
Displayed values are rounded as specified by the mode
setting with a maximum of 10 digits and a two-digit
exponent.
•
RegEQ
displays up to 14 digits in
Float
mode. Using a
fixed-decimal setting other than
Float
causes
RegEQ
results to be rounded and stored with the specified
number of decimal places.
Xmin
is the center of the leftmost pixel,
Xmax
is the center
of the next-to-the-rightmost pixel. (The rightmost pixel is
reserved for the busy indicator.)
@
X
is the distance
between the centers of two adjacent pixels.
•
In
Full
screen mode,
@
X
is calculated as
(
Xmax
N
Xmin
)
à
94. In
G
.
T
split-screen mode,
@
X
is
calculated as (
Xmax

Xmin
)
à
46.
•
If you enter a value for
@
X
from the home screen or a
program in
Full
screen mode,
Xmax
is calculated as
Xmin
+

T
split-screen mode,
Xmax
is
calculated as
Xmin

46.
Ymin
is the center of the next-to-the-bottom pixel;
Ymax
is
the center of the top pixel.
@
Y
is the distance between the
centers of two adjacent pixels.
•
In
Full
screen mode,
@
Y
is calculated as
(
Ymax

Ymin
)
à
62. In
Horiz
split-screen mode,
@
Y
is
calculated as (
Ymax

Ymin
)
à
30. In
G
.
T
split-screen
mode,
@
Y
is calculated as (
Ymax

)
à
50.
•
If you enter a value for
@
Y
from the home screen or a
program in
Full
screen mode,
Ymax
is calculated as
Ymin
+
@

split-screen mode,
Ymax
is
calculated as
