....Type maps are discussed below in section 3.4 of this chapter. 19 bits is the largest number of bits that can reasonably be allocated for a type map number while still making the value a 64 bit IEEE signaling NaN and leaving room for other tagged values. A LISP system has been built by Umemura[Ume91] that represents LISP tagged CHAPTER 3. DATA TYPES 78 data as 64 bit VAX floating numbers. Pointers (without type map numbers) are represented by invalid floating point numbers that cause traps when input to arithmetic operations. In this LISP system, the integer 1 and the floating point number ....
