data study;
input Subj : $3.
Group : $1.
Dose : $4.
Weight : $8.
Subgroup;
x= input(Weight,5.1);
datalines;
001 A Low 220 2
002 A High 90 1
003 B Low 193.6 1
004 B High 165 2
005 A Low 123.4 1
;

Why does X get truncated? X shows up as 22 instead of 220,9
instead of 90 and 19.8 instead of 198? This problem doesnt
happen with the values 193.6 and 123.4.

This does not happen if x is read on the 5. informat instead
of the 5.1 informat

Answer / kumaraswamy maduri

Informat 5.1 or 5.2 tell the SAS processor to allocate
specified number of decimals from right to left of the
value and the remaining to the number.
Informat 5. is good if you have one decimal even this fails
when you have more than one decimal.
