Writes positive integer binary (fixed-point) values in Intel and
DEC formats.
-
w
-
specifies the width of the input field.
-
d
-
specifies to multiply the number by 10d. This argument is optional.
All values are treated as positive. PIBRw.d writes positive integer
binary
values that have been generated by and for Intel and DEC operating environments.
Use PIBRw.d to write
positive integer binary data from Intel or DEC environments on other operating
environments. The PIBRw.d
format in SAS code allows for a portable implementation for writing the data
in any operating environment.
Note: Different operating
environments store positive 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)

Positive integer binary values are the same as
integer binary values except that the sign bit is part of the value, which
is always a positive integer. The PIBRw.d format treats all values as positive and includes the sign
bit as part of the value.
-
The PIBRw.d format with a width of 1 results in a value that corresponds
to the binary equivalent of the contents of a byte. A value that corresponds
to the binary equivalent of the contents of a byte is useful if
your data contain values between hexadecimal 80 and hexadecimal FF, where
the high-order bit can be misinterpreted as a negative sign.
-
On Intel and DEC operating environments, the
PIBw.d and PIBRw.d formats are
equivalent.
-
The IBw.d and PIBw.d
formats are used to write native format integers. (Native format allows you
to read and write values that are 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.

The result is a hexadecimal representation of a two-byte
binary number written in positive integer binary format, which occupies one
column of the output field. |
