Reads native integer binary (fixed-point) values, including negative
values.
-
w
-
specifies the width of the input field.
-
d
-
specifies the power of 10 by which to divide
the value. This argument is optional.
The IBw.d informat reads integer binary (fixed-point) values, including
negative values represented in two's complement notation. IBw.d reads integer binary values
with consistent results if the values are created in the same type of operating
environment that you use to run SAS.
Note: Different
operating environments store integer binary values in different ways. This
concept is called byte ordering. For a detailed discussion about byte ordering,
see
Byte Ordering for Integer Binary Data on Big Endian and Little Endian Platforms.

The
IBw.d and PIBw.d
informats are used to read native format integers. (Native format allows you
to read and write values created in the same operating environment.) The IBRw.d and
PIBRw.d informats are used to read little endian integers in any
operating environment.
To view a table that shows the type of informat to use
with big endian and little endian integers, see
SAS Informats and Byte Ordering.
To view a table that compares integer binary notation
in several programming languages, see
Integer Binary Notation and Programming Languages.
You can use the INPUT statement and specify the IB informat.
However, these examples use the informat with the INPUT function, where binary
input values are described using a hexadecimal literal.
x=input('0080'x,ib2.);
y=input('8000'x,ib2.);
