Summation on HP 42S

[lrdheat]

Wow! I love seeing the math employed in contrast to just doing a simple, mindless, addition loop to get to the answer.

The Free42 handles 1000! Without out of range error. The WP 34S handles it (high is displayed in the power of 10 display, but asking for a full display with left pointing yellow carrot symbol shows the exponent of 10 along with the first 34 digits of 1000! blue right pointing carrot gives final portion of 34 digits).
