Informats under z/OS

RBw.d Informat: z/OS

Reads real binary (floating-point) data.

Numeric
Width range:	2- 8 bytes
Default width:	4
Decimal range:	0-10
z/OS specifics:	IBM floating-point format
See:	RBw.d Informat in SAS Language Reference: Dictionary

Details

The w value specifies the number of bytes, not the number of digits. If the informat specification includes a d value, the number is divided by 10^d.

The format of floating-point numbers is host-specific. See the data representation information in SAS Language Reference: Concepts for a description of the IBM floating-point format that is used under z/OS.

The following examples show how data that represent decimal numbers are read as floating-point numbers using the RBw.d informat:

Data Line (Hexadecimal)	Informat	Value	Notes
434CE00000000000	rb8.1	123	a d value of 1 causes the number to be divided by 10¹
44300C0000000000	rb8.2	123	a d value of 2 causes the number to be divided by 10²
C27B000000000000	rb8.	-123
434D200000000000	rb8.	1234
41C4000000000000	rb8.	12.25

Note: In these examples, Data Line (Hexadecimal) represents the bit pattern stored, which is the value you see if you view it in a text editor that displays values in hexadecimal representation. Value is the number that is used by SAS after the data pattern has been read using the corresponding informat. [cautionend]
