Casio fx-991CW

One difference I see in the manual is that if using line instead of MathPrint, when integrating and choosing a tolerance (epsilon), the EX must use a tolerance no smaller than 10^-14. The new edition states that a tolerance no smaller than 10^-22 must be used. Wonder if that would make the calculator better equipped to use a number closer to an undefined value as an endpoint in an integration than the EX. Also, perhaps this would allow more decimal results to be converted to fractions…
