• Precision is basically the same as that described under “Calculation
Range and Precision”, above.
• Calculations that use any of the functions or settings shown below
require consecutive internal calculations to be performed, which can
cause accumulation of error that occurs with each calculation.

• Error is cumulative and tends to be large in the vicinity of a function’s
singular point and inflection point.
• During statistical calculation, error is cumulative when data values
have a large number of digits and the differences between data values
is small. Error will be large when data values are greater than six
digits.
Error Messages
The calculator will display an error message whenever an error occurs
for any reason during a calculation.
• Press d or e to return to the calculation screen. The cursor will be
positioned at the location where the error occurred, ready for input.
Make the necessary corrections to the calculation and execute it
again.
• Press A to return to the calculation screen. Note that this also clears
the calculation that contained the error.
Math ERROR
Cause: • The intermediate or final result of the calculation you
are performing exceeds the allowable calculation range. • Your
input exceeds the allowable input range. • The calculation you
are performing contains an illegal mathematical operation (such as
division by zero).
Action: • Check the input values and reduce the number of digits.
• When using independent memory or a variable as the argument of
a function, make sure that the memory or variable value is within the
allowable range for the function.
