Details

On an IBM mainframe system, integer values are represented in two's complement notation. If the informat specification includes a d value, the number is divided by 10^d.

Here are several examples of the IBw.d informat:

Data Line (Hexadecimal)	Informat	Value	Notes
FFFFFB2E	ib4.	-1234
000000003034	ib6.2	123.4	a d value of 2 causes the number to be divided by 10²
00000001E208	ib6.2	1234	a d value of 2 causes the number to be divided by 10²

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]
