Writes native integer binary (fixed-point) values, including negative
values.
-
w
-
specifies the width of the output field.
-
d
-
specifies to multiply the number by 10d. This argument is optional.
The IBw.d
format writes integer binary (fixed-point) values, including negative values
that are represented in two's complement notation. IBw.d
writes 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. ![[cautionend]](../../../../common/63294/HTML/default/images/cautend.gif)
The IBw.d and
PIBw.d
formats are used to write native format integers. (Native format allows you
to read and write values created in the same operating environment.) The IBRw.d and
PIBRw.d formats are used to write little endian integers in any operating
environment.
To view a table that shows the type of format to use
with big endian and little endian integers, see
SAS Formats and Byte Ordering.

in several programming languages, see

The result is a hexadecimal representation of a four-byte
integer binary number. Each byte occupies one column of the output field. |
