Returning NaN might indeed make thing more stable. I think returning all NaNs instead of throwing would be much better > behavior. > I completely agree. Going with Benoit's suggestion, we can change the idl for invert to: bool invert(); and change inverse to return a matrix with NaN for all its elements. _______________________________________________ dev-platform mailing list [email protected] https://lists.mozilla.org/listinfo/dev-platform
