Errors and Calculation Ranges
Errors
An error will occur if an operation exceeds the calculation rang-
es, or if a mathematically illegal operation is attempted. When
an error occurs, pressing
g
or
y
automatically moves
the cursor back to the place in the equation where the error oc-
curred. Edit the equation or press
s
to clear the equation.
Note: If an error occurs during the automatic calculation of a
listed fi nancial variable, pressing
s
,
g
, or
y
displays the fi rst variable in the function.
