error and confidence interval in leasqr

Hello,
sorry if it looks silly, but how can i calculate the fitting error for a
certain confidence interval in leasqr, like:

F = @(x,p) p(1)*exp(-p(2)*x);
[f1, p1, kvg1, iter1, corp1, covp1, covr1, stdresid1, Z1, r21] = ...
leasqr(var1, var2, pin, F );

printf("p(2) = %.3f  +-  %.3f for %d%% confidence", p(2), ?, ?)


A second question is how to make the p(2) value and the error
agree in number of decimal points, ie how to define %.3f  in
printf if the necessary number of decimal points can change
from problem to problem. Is there a routine to automate that?

Thanks a lot in advance ...
