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 1EL5; ‰f(x)dx is calculated at
1EL3. 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.
