[tex-k] Wording improvement on A275

[Karl Berry]

Hi Yajie,

    A275, line -2 speaks of "explicit character tokens whose category
    codes are respectively of types 1 and 2". But nowhere else in the book
    are category codes further grouped into types. 

Thanks for the report. Will consult.

    Actually 52.3 is 37*sqrt(2) computed to one decimal place, so I think
    Knuth intended to compute 36*sqrt(2) electronically but typed 37.

Sounds probable. Will update, thanks. -k
