## Known issuesSome calculations (such as taking the inverse of zero) produce NaN as an output. Others may produce ∞ (for example, through arithmetic overflow). These can be used in calculations, but I have not checked the correctness of the calculator arithmetic using infinities and NaNs.
The trigonometric functions are set to return an error if the argument or result is a complex
number with nonzero imaginary part and the mode is set to degrees. This is because I
don’t know of a meaningful way to convert degrees to radians and The code for variable expressions is not (at May 2008) tested thoroughly and there are some minor issues in automatic simplification of expressions. Although simplified expressions are (as far as I know) all correct, the order of summands in a polynomial is not always correct.
The code for graphs is not (at May
2008) complete. Most simple graphs will display correctly,
but there are some unresolved issues. At May 2008 the graph
