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)
Ã
94. In G
.
T split-screen mode,
@
X
is
calculated as (Xmax
N
Xmin)
Ã
46.
•
If you enter a value for
@
X
from the home screen or a
program in Full screen mode, Xmax is calculated as
Xmin +
@

…
94. In G
.
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
N
Ymin)
Ã
62. In Horiz split-screen mode,
@
Y
is
calculated as (Ymax

Ymin)
Ã
30. In G

T split-screen
mode,
@
Y
is calculated as (Ymax

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