Details

On an IBM mainframe system, integer values are stored in two's complement notation.

If an overflow occurs, the value written is the largest value that fits into the output field; the value will be positive, negative, or unsigned, as appropriate. If the format includes a d value, the number is multiplied by 10^d.

Here are some examples of the IBw.d format:

Value	Format	Results (Hexadecimal)	Notes
-1234	ib4.	FFFFFB2E
12.34	ib4.	0000000C
123456789	ib4.	075BCD15
1234	ib6.2	00000001E208	a d value of 2 causes the number to be multipled by 10²
-1234	ib6.2	FFFFFFFE1DF8	a d value of 2 causes the number to be multipled by 10²
1234	ib1.	7F	overflow occurred
-1234	ib1.	80	overflow occurred

Note: In these examples, the Value column represents the value of the numeric variable. 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]
