d: specifies the number of digits to the right of the decimal point in the numeric value.

Details

The ZDw.d format writes zoned decimal data. This method is also known as an overprint trailing numeric format. In the Windows operating environment, the last byte of the field contains the sign information of the number. The following table gives the conversion for the last byte.

Digit	ASCII Character	Digit	ASCII Character
0	{	-0	}
1	A	-1	J
2	B	-2	K
3	C	-3	L
4	D	-4	M
5	E	-5	N
6	F	-6	O
7	G	-7	P
8	H	-8	Q
9	I	-9	R

Examples

Example 1: Processing a Number That Is Too Large To Format

When a numeric value is too large to format, as in this example

data a;
   x = 1e308;
   y = put(x, ZD32.2);
   put y = hex16.;
run;

the result is a sequence of 39s:

y=3939393939393939
