HEXw.

Numeric
Width range:	1-16 bytes
Default width:	8
Alignment:	left
OS/390 specifics:	writes output as EBCDIC, IBM floating-point format

Details

Each hexadecimal digit is written using the EBCDIC code, which requires one byte per digit. See EBCDIC Code: Commonly Used Characters for a table of commonly used EBCDIC characters.

The format of floating-point numbers is host-specific. See Representation of Floating-Point Numbers for a description of the IBM floating-point format that is used under OS/390.

The w value of the HEXw. format determines whether the number is written as a floating-point number or as an integer. When you specify a width value of 1 through 15, the real binary numbers are truncated to fixed-point integers before being converted to hexadecimal representation. When you specify 16 for the width, the floating point values are used, and the numbers are not truncated.

The following examples illustrate the use of HEXw. under OS/390:

Value		Format	Results	Notes
31.5		hex16.	421F800000000000	floating-point number
31.5		hex15.	00000000000001F	integer
-31.5		hex16.	C21F800000000000	floating-point number
-31.5		hex15.	FFFFFFFFFFFFFE1	integer

Note:   In these examples, the Value column represents the value of the SAS numeric variable. The Results column shows what the numeric value looks like when viewed from a text editor.
