bug#30877: 25.3; Floating numbers rounded

[Eduardo Suarez-Santana]

Running
$ emacs -q --eval "(message (number-to-string 2.33333))"
prints '2.0'. That breaks some package loading.

However, it works with '-nw' (text mode).

This is most probably bug#30788, caused by fontconfig.

(I cannot reproduce this on a system that doesn't use fontconfig.)

Yes, it's a duplicate.
