IBRw.d Format

Syntax Description

w

specifies the width of the output field.

Default:	4
Range:	1-8

d

specifies to multiply the number by 10^d. This argument is optional.

Default:	0
Range:	0-10

The IBRw.d format writes integer binary (fixed-point) values, including negative values that are represented in two's complement notation. IBRw.d writes integer binary values that are generated by and for Intel and DEC operating environments. Use IBRw.d to write integer binary data from Intel or DEC environments on other operating environments. The IBRw.d format in SAS code allows for a portable implementation for writing the data in any operating environment.

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 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, regardless of the operating environment you are writing on.

• In Intel and DEC operating environments, the IBw.d and IBRw.d formats are equivalent.
