If I add a tolerance value: \( \int \)(e^X,0,500,0.01) I get 1.000000014 in about 0.5 seconds for tolerance values of 0.009 to 0.1724, and 1.000050478 (for a tolerance value of >0.1724 to 0.66558). Larger tolerance values affect the result more. It'd be interesting to see whether the 991EX has this tolerance value in the formula it uses.

My HP50G gave me \(\frac {e^{500}1}{e^{500}} \) instantly instead of \(  \frac {1e^{500}}{e^{500}} \) when I hit EVAL from the equation writer. I presume those two are equivalent. I also observed the Approx/Exact discrepancy. (Post 258) Regards, BrickViking HP50g Casio fx9750G+ Casio fx9750GII (SH4a)
