IBw.d

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

Details

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 .

Comparisons

The IBw.d and PIBw.d formats are used to write native format integers. (Native format enables 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 Writing Data Generated on Big Endian or Little Endian Platforms.

Example

y=put(x,ib4.);
put y $hex8.;

Value of `x`	Result on Big Endian Platforms 1	Result on Little Endian Platforms 1
	----+----1	----+----1
128	00000080	80000000
1The result is a hexadecimal representation of a four-byte integer binary number. Each byte occupies one column of the output field.
