Improper Integrals with the HP-15C LE & CE

[Johnh]

I tried the 1 / (sqrt x) integral on my 15C CE, and a couple of 15C emulators, with very variable results!

The real 15C CE performed the same as described above, as each FIX setting, basically 1.999.....etc

But two versions of Touch 15i for Android returned 2.012658, consistently subject to the number of digits requested, and never got nearer to 2.

The Jovial JRPN 15C doesn't seem to settle on a value, even at just 2 or 3 decimal places
