Ranges of Predefined Data Types

Table 4-2 “Ranges and Sizes of Predefined HP Pascal Types ” gives the range and size of each predefined data type available to HP Pascal. The data types are in alphabetical order and the sizes are in bits. To get a size in bytes, divide the number of bits by eight.

Table 4-2 Ranges and Sizes of Predefined HP Pascal Types

Type	Range	Unpacked Size in Bits
Bit16	`0..65535`	16
Bit32	`0..2³²-1`	32
Bit52	`0..2⁵²-1`	64
Boolean	FALSE or TRUE, where FALSE=0 and TRUE=1	8
Char	ASCII character set	8
Integer	`-2`³¹..`2`³¹`-1`	32
Longreal	`-1.79769313486231510`³⁰⁸`..-4.94065645841246610`^-324, `0`, `4.94065645841246610`^-324`..1.79769313486231510`³⁰⁸	64
Real	`-3.40282310`³⁸`..-1.40129810`^-45, `0`, `1.40129810`^-45`..3.40282310`³⁸	32
Shortint	`-32768..32767`	16
Longint	`-2⁶³..2⁶³-1`	64

The range of values for longreal and real include denormalized numbers.




	NOTE: HP and IEEE floating point numbers are identical. HP3000_16 floating point numbers are different from HP and IEEE floating point numbers. For details, refer to the Introduction to MPE XL for MPE V Programmers.
