Why the 32/64 bit confusion?

For some reason there’s an ongoing confusion about the following matrix :

Native 32 bit floating point calculations Native 64 bit floating point calculations
32 bit memory addressing X X
64 bit memory addressing X X

So, all combinations work but people regularly (even developers) have the misconception that 64 bit floating point calculations somehow
must involve a 64 bit CPU architecture (and by extension, a 64 bit operating system).
