Aha! Yes, that must be it.

It doesn't operate on every line separately. However, it does operate
like Perl's s/xxx/yyy/g which is why it's called sg. The g is for
"global". After making one change, it seeks further down the string for
further matches.

It might be as well to anchor the regex too, just to be on the safe
side:

${sg {100.0\n100.0} {\N^(?s)(\d+).*\N} {\$1}}
