The format of floating-point numbers is host-specific. See SAS Language Reference: Concepts for a description of the format that is used to store floating-point numbers under z/OS.

If the format includes a d value, the number is multiplied by 10^d.

Here are some examples of how decimal numbers are written as floating-point numbers using the RBw.d format:

Value	Format	Results (Hexadecimal)	Notes
123	rb8.1	434CE00000000000	a d value of 1 causes the number to be multiplied by 10¹
123	rb8.2	44300C0000000000	a d value of 2 causes the number to be multiplied by 10²
-123	rb8.	C27B000000000000
1234	rb8.	434D200000000000
1234	rb2.	434D	truncation occurred
12.25	rb8.	41C4000000000000

Note: In these examples, the Value column represents the value of the data, and the Results column shows a hexadecimal representation of the bit pattern written by the corresponding format. (You cannot view this data in a text editor, unless you can view it in hexadecimal representation.) [cautionend]
