It would make sense if scanf() had the equivalent flag
to printf() to
make number printing and parsing at least potentially orthogonal.
That is not an easy thing to do because of local (er, locale:)
conventions. See
https://docs.oracle.com/cd/E19455-01/806-0169/overview-9/index.html for
examples.
Having a canonical input and output format, which is converted by filters
just before/after the human sees the numbers, seems the only way to make
this work globally.
