Each operation is accurate to ±1, in the 10th digit.
However, calculations involving multiple operations
will cause the error to accumulate. This is also
observed with internal calculations involving multiple
operations such as ^(
like.
Note that the error may be greater near an inflection
point of a function.
Sequence of Operations
Calculations are carried out in the following order:
1. Coordinate transformations:Pol(
2. A-type functions: These are functions where a value
must be entered before you press a function key.
