The version that I have appears to have _ parsed as an operator in addition to the negation of a numeric constant.

I'm using the version from Debian testing:

    dc -V
    dc (GNU bc 1.07.1) 1.4.1

In fact, in my version "-v" as opposed to "-V" isn't recognized as a valid option.

I am Gavin Howard, the author of the other dc.

My dc does have a few differences from the GNU dc. I added the extension of using _ as a negative sign.

That is why you are both seeing behavior differences.

I am the author of that dc.

You are correct about its behavior.

See https://git.gavinhoward.com/gavin/bc/src/branch/master/manua... (scroll down to the underscore command).
