Description aziem 2008-01-05 17:34:29 UTC

In OOo 680m238 (pre-2.4.0) I display the regression function for an exponential
curve (recently implemented in issue 7998).   OOo gives the function
f(x)=26.45*1.03^x while Excel 2003 gives y=26.445*e^(0.0252*x). When I work off
both of these, OOo's displayed equation does not match the data well.  Could OOo
please show a little more precision?

The shown precision can be set in the dialog page "Number" of the properties dialog of the equation.

Complains about not sufficient accuracy need an example. I close this issue for now.
