•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
