forbid scientific notation in numfmt #11655

[Devel08]

This PR forbids scientific notation in input of numfmt and should resolve #11655. Sorry for opening and closing so much PR's, but I am new in using git with github. That'll be the last one, I swear!
Passes all checks with cargo test .
Thanks!

Can you please enable the corresponding test in tests/by_util/test_numfmt.rs and run cargo fmt? Thanks.

@cakebaker Done, I even edited my solution a bit, I enabled the test, but I think errormsg's name may not sound good, however, I'll wait for your review!
