| Default: | 4 |
| Range: | 1-8 |
| 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 on Big Endian and Little Endian Platforms. ![[cautionend]](../common/images/cautend.gif)
| Comparisons |
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.
To view a table that compares integer binary notation in several programming languages, see Integer Binary Notation and Programming Languages.
