I don't really see how you can say that "to posit" is the opposite of "to negate".
?? "To put forward as fact" seems like the opposite of "to contradict" to me. One says, "it's true!" The other, "it's false!"
The only other term that I have found that is acceptable for the unary plus operator is "unary_plus." That just seems so ... boring. ;-) And a little strange to have "negate" and "unary_plus". Blech.
Is there a mathematician who can tell me if the operation performed by the unary plus operator has a name?
What about identity? ;) just-kidding-ly-yours, -- gpd
