Floating-Point NumbersFloating-point numbers are listed in a separate list. Afloating-point number is put on this list either as it is readin or as it is generated within a calculation. Neither thislist nor the list of atomic symbols has any duplications. Anassociation list is created for a floating-point number whenthe number is put on the list of numbers.The association list for floating-point numbers containsthe indicators NUMB and FLO (for floating-point), but the indicatorPNAME is not put on the list until a request for printingthe number is encountered. Only positive numerical valuesare put on the association listsfor floating-point numbers; ifa number is negative the association list for the number ispreceded by the indicator MINUS, and the entry in the list offloating-point numbers points to the MINUS indicator. Thus wehaveJust as a matter of interest we give below the associationlists for atom and for the constant 1, just as they are representedin the 704. We use the bar notation, add, to represent
the 2's (8's) complement of an octal address.*Preceding all the individual association lists in the 704<strong>LISP</strong> I system is the list of all atomic symbols. Each registerof this list has an entry of the formwhere x is the address of the first register of the associationlist for this atomic symbol, and y is the address of the nextentry in the list of atomic symbols. Thus for - atom whose associationlist starts in 25146 the entry in the list of atomicsymbols islocationentry24657 0531.20052632representing25146, ,-The association lists which appear in the following areatomic symbollocation of association listpname(integer) - int- atom25146constant 1subrapval*-The term "findex" is sometimes used for the 2's complementof an octal location.
