I personally think that if the object of printing the constant is to recreate
the source code, but the source code won't match anyway, then it is better to
not print it at all. If the goal of printing is some other (debugging, dump
files, ...), then it may make sense.

Another issue is that if someone comes around a fixes PR49152, then your
testcase for printing floating point constants nicely would be broken. Has this
person to come up with a new testcase for this? delete the testcase? It just
makes PR49152 slightly harder to fix.
