Big news from Casio at September NCTM

[lrdheat]

I wonder if the 100 will use, internally, numbers down to between 10^-17 and 10^-21, depending on the problem, much as the fx-991CW does. So far, the CASIO’s cannot integrate many problems that have an undefined point in the domain, even though the integral value exists. The work around is moving away from the undefined point by 10^-17 or 10^-16 in the case of the fx-991CW, 10^-12 for the fx-CG50, the 9750giii. Also wonder if complex mode will be more complete, will support trigonometric and exponential functions…
