NumericFocus parameter controls the degree to which the
code attempts to detect and manage numerical issues. The default
setting (0) makes an automatic choice, with a slight preference for
speed. Settings 1-3 increasingly shift the focus towards being more
careful in numerical computations. With higher values, the code will
spend more time checking the numerical accuracy of intermediate
results, and it will employ more expensive techniques in
order to avoid potential numerical issues.
