Appendix B: General Information 177
• 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 N 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 + @X É… 94. In G-T split-
screen mode, Xmax is calculated as Xmin + @X É… 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) à 62. In Horiz
split-screen mode, @Y is calculated as (Ymax N Ymin) à 30. In G-T
split-screen mode, @Y is calculated as (Ymax N Ymin) 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 + @Y É… 62. In Horiz
split-screen mode,
Ymax is calculated as Ymin + @Y … 30. In G-T split-
screen mode, Ymax is calculated as Ymin + @Y É … 50.
Cursor coordinates are displayed as eight-character numbers (which may
include a negative sign, decimal point, and exponent) when Float mode
is selected. X and Y are updated with a maximum accuracy of eight
digits.
minimum and maximum on the CALCULATE menu are calculated with a
tolerance of 1âL5; ‰f(x)dx is calculated at 1âL3. Therefore, the result
displayed may not be accurate to all eight displayed digits. For most
functions, at least five accurate digits exist. For
fMin(, fMax(, and fnInt(
on the MATH menu and solve( in the CATALOG, the tolerance can be
specified.
