Is that so?  I see Wikipedia claims it is, but there are no sources for that 
claim.  (There is an assertion that it is "discussed at length on the talk 
page" of an article about number representation, but in fact there is no 
discussion there at all.)

I have never seen this spelling before, and I very much doubt its validity.  
For one thing, why then have "two's complement"?  For another, to pick one 
random authority, J.E. Thornton in "Design of a computer -- the Control Data 
6600" refers to "one's complement" to describe the well known mode used by that 
machine and its relatives.
