-Perl has two kinds of array, numerically-indexed and associative. Awk
-arrays are usually translated to associative arrays, but if you happen
-to know that the index is always going to be numeric you could change

Awk starts by assuming OFMT has the value %.6g. Perl starts by
assuming its equivalent, $#, to have the value %.20g. You'll want to
