2False convergence tolerance
3Description::
4\c false_conv_tol (NL2SOL's \c xftol) is the
5false-convergence tolerance (stop with a suspicion of discontinuity
6when a more favorable stopping test is not satisfied and a step of
7scaled length at most \c false_conv_tol is not accepted)

9The internal default is a function of machine epsilon
10(as limited by \c function_precision). The default is selected with a value of -1.
