Logarithmic Regression: Different correlation from 3 different calculators

[groundbeef]

Just another data point for you - my Casio fx-9750GII gives 0.96837274.

It shows the regression results in a 10 character space, and I can't figure out how to get any more digits out of it.

Also, I'm sure you've checked this, but it took me three tries to get all the numbers entered correctly (and that's with the list display). When I had transposed the 2 and 7 in 58372, I got 0.96835999, pretty close to your TI-36X number.

And a question - I'm really weak in my stats knowledge, but is there any possible reason why more that 2 or maybe 3 significant figures for this value would matter? Of course, playing with numbers is its own fun.
