Microchip math file FLO3232U

Is it supposed to be recent?

The first math related files I ever searched were from almost 30 years in their ANs.

Well, their C17 compiler is ancient and that is the only reference I can find to it, so I would say that it is not recent.

Unfortunately, I can't download the compiler (their website says no) to see if it is included as one of the files.

Managed to find a pdf that lists the C17 libraries dated 2002 and the U means unsigned (there is also an S version = signed), the FP32.A16 file dates to the late 90's, so I'm guessing the U means there is an updated version somewhere (although still old).

The one I was reading was http://ww1.microchip.com/downloads/en/appnotes/00660.pdf

Yeh, that one deals with advanced math functions, AN575 is the basic add. subtract, multipy , divide one.

I am confused. Are you looking for AN575, which has that routine without any Uor S, the C17 compiler, or something else (e.g., that specific unsigned routine)?

AN575 is here: http://ww1.microchip.com/downloads/en/AppNotes/00575.pdf

Edit:
Here's part of what Grok3 has to say about C17:

If you’re working on a legacy project with PIC17 devices, you may need to source the C17 compiler from archived Microchip resources or contact Microchip support, as it’s not readily downloadable. For new projects, transitioning to PIC18 devices with the XC8 compiler is advisable due to better support and availability.

What I'm trying to find out is what the difference is between the U and non-U versions and which include file that contains them is the newest one.

So far, I can only find the include file that contains the non-U version and that is the code associated with AN575, which I have.
