Hello,
Does someone know how many significant digits do we have using a PD.6 format.
Could it be possible to get a table showing the number of significant digits for each PD.x format.
Regards,
I ran this test:
data test;
length checkvar $12;
input number;
checkvar = put(put(number,pd6.),$hex12.);
datalines;
123456789
-123456789
1234567890
-1234567890
12345678901
123456789012
1234567890123
;
proc print data=test;
run;
and got this result:
Beob. checkvar number 1 000123456789 123456789 2 800123456789 -123456789 3 001234567890 1234567890 4 801234567890 -1234567890 5 009999999999 12345678901 6 009999999999 123456789012 7 009999999999 1234567890123
So it can be seen that a full byte is reserved for the (possible) sign. This behavior is described in the OS-specific documentation of the PD format:
Digits or significant digits? Not the same thing. The significant digits are use specific.
The W is the number of BYTES in the output, and each byte has two digits. So PD6. = 12 digits.
Try it:
length checkvar $12;
checkvar = put(put(1234567123456,pd6.),$hex12.);
You are not starting with a packed decimal value.
