IBw.d Informat

Syntax Description

w

specifies the width of the input field.

Default:	4
Range:	1-8

d

specifies the power of 10 by which to divide the value. This argument is optional.

Range:

0-10

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.);

put x=;

128

-32768

put y=; 

-32768

128
