But try

data _null_; format x 8.1; do x = 3, -1234567890.123, 12345678901234567890; y = index(x,'.'); put x=best12. y =; end; run;

You should see

x=3 y=0 x=-1234567890 y=0 x=1.2345679E19 y=2

If you refine the technique by making the numeric-to-character conversion explicitly and using the BEST32 format, such errors should be extremely rare.
