The flags here are passed to a private QVariant constructor, and they
really represent a boolean - IsPointer or not.
Because the flag for the key_type was incorrectly populated with the
flag for the value_type, memory would be corrupted when using a mapping
type whose value_type is a pointer, but whose key type was not, such as
QMap<QString, int*>
This typo has been there since the concept was introduced in commit
v5.2.0-alpha1~807 (Add container access functionality for associative
containers in QVariant., 2013-04-05).

Not just fuzzily equal. The fuzzy comparison fails for infinities, since
the expression p1 - p2 where p1 = p2 = infinity is NaN. And NaN
comparisons are always false.
As a nice side-effect, we don't do the more expensive computation of a
multiplication if the two numbers really are equal.

Previously, QVariant would try to convert one operand to the other's
type, which would produce unexpected results: the results would depend
in the order of the operands and whether there was data loss in the
conversion. In addition, ordering comparisons were only done with signed
values, yielding other unexpected results, like
QVariant(LLONG_MAX / 2) < QVariant(Q_UINT64_C(0)).
Instead, try to obey the C++ standard rules for type promotion in
expressions. Our code is a little simpler than the standard would seem
to require since we know some more details from the ABI.
[ChangeLog][Important Behavior Changes][QVariant] QVariant now obeys the
C++ type promotion rules when comparing numeric types (integrals, float
and double), including the fact that unsigned comparisons are preferred
for types of the same rank (that is, now QVariant(-1) > QVariant(0U)).

This would result in (a == b) != (b == a). The == operation should be
commutative as much as possible.
Now, there's still an asymmetry in that b is forced to a type and the
conversion may fail. QVariant should have an idea of what conversions
are "promotion" and which ones are "demotion" (subject to loss of data
and/or can fail), so it can do the promotion first

This now guarantees that doing a round-trip from an FP number to string
and back to number results in the same number. This change is required
because DBL_DIG and FLT_DIG don't have the meaning that we were
expecting them to, here: they mean the minimum number of digits of
precision in decimal (i.e., changing the last decimal will always cause
the FP number to change). We need the maximum number: there is one
change in the last decimal place that causes the FP number to change.
IEEE 754 single-precision has 24 binary digits and double precision has
53 binary digits in their mantissa. To convert that to decimal, multiply
by the number of decimal digits a binary digit represents (log2(10) =
0.3), then add one for the rounding and one more digit for the actual
precision we want. That is, for floats we now ask for 9 digits and for
double, 17 decimal digits.
