Can the spreadsheet salvage the 991CW

[lrdheat]

I noticed on the SwissMicros forum where a discussion on the WP 34S dealing with the accuracy of its integration of e^(cos(x) * sin(x)) from 0 to 100. The actual value is 106.49243824200123… on the 991EX, 9750 giii, and CG-50, the answer comes up as 106.4923778, incorrect beginning with the 4th decimal. Interestingly, the 991CW comes up with 106.4924382, and when I subtract 106.4924382 from this, I get the rest of what was in the result internally, namely 4.200123*10^-08 which is right on target! I imagine that this is due to the CW doing calculations internally to 10^-17 to as fine as 10^-22.
