Details

The w value specifies the number of bytes, not the number of digits. If the informat specification includes a d value, the number is divided by 10^d.

In packed decimal format, each byte except for the last byte represents two decimal digits. (The last byte represents one digit and the sign.) An IBM packed decimal number consists of a sign and up to 31 digits, thus giving a range from -10³¹ + 1 to 10³¹ - 1. The sign is written in the rightmost nibble. (A nibble is 4 bits or half a byte.) A hexadecimal C indicates a plus sign, and a hexadecimal D indicates a minus sign. The rest of the nibbles to the left of the sign nibble represent decimal digits. The hexadecimal values of these digit nibbles correspond to decimal values; therefore, only values between '0'x and '9'x can be used in the digit positions.

Here are several examples of how data is read using the PDw.d informat:

Data Line (Hex) Informat Value Notes

01234D pd3. -1234

0123400C pd4.2 1234 the d value of 2 causes the number to be divided by 10²

Data Line (Hex)	Informat	Value	Notes
01234D	pd3.	-1234
0123400C	pd4.2	1234	the d value of 2 causes the number to be divided by 10²

Note: In these examples, Data Line (Hex) represents the bit pattern stored, which is the value you see if you view it in a text editor that displays values in hexadecimal representation. Value is the number that is used by SAS after the data pattern has been read using the corresponding informat. [cautionend]
