+ \macro QT_NO_FLOAT16_OPERATORS
+ \relates <QFloat16>
+ \since 5.12.4
+
+ Defining this macro disables the arithmetic operators for qfloat16.
+
+ This is only necessary on Visual Studio 2017 (and earlier) when including
+ \c {<QFloat16>} and \c{<bitset>} in the same translation unit, which would
+ otherwise cause a compilation error due to a toolchain bug (see
+ [QTBUG-72073]).
