9ae3a8
We never actually stored the stringified double values into the strings
9ae3a8
before we did the comparisons. This left number/double values completely
9ae3a8
uncovered in test-visitor-serialization tests.
9ae3a8
9ae3a8
Fixing this exposed a bug in our handling of large whole number values
9ae3a8
in QEMU's JSON parser which is now fixed.
9ae3a8
9ae3a8
Simplify the code while we're at it by dropping the
9ae3a8
calc_float_string_storage() craziness in favor of GStrings.
