diff <(awk -e 'BEGIN{ x = 1; for(i=1;i<1025;++i) { x = x * 2; print i,
x } }') <(awk -M -e 'BEGIN{ x = 1; for(i=1;i<1025;++i) { x = x * 2;
print i, x } }')

Now, it shows the difference.

But it is still better to have a direct way to show the type info of
variables used in awk instead of using this indirect way. Is there a
direct way? Thanks.
