Interesting. I guess the first case doesn't matter, as rounding -inf gives -inf.

If the second was used in error, I guess it might have shown up spectacularly, but I'd have to follow through the subsequent actions properly

I can also run the entire test suite for this change, if you like. Just to see if any problem is affected...

I started testing and will report back tomorrow.
