PIBRw.d Format

Writes positive integer binary (fixed-point) values in Intel and DEC formats.

Category:

Numeric

Syntax

PIBRw.d

Syntax Description

w: specifies the width of the input field.

Default:1

Range:1–8

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

Default:0

Range:0–10

Details

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 .

Comparisons

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 enables 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.

Example

y=put(x,pibr2.);
put y $hex4.;

Value of `x`	Result 1
	----+----1
128	8000
1The 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.
