there is no FPU socket on the A1200 motherboard.
There sort of is. Commodore planned to make 1200s available with an onboard-FPU as an option, but never did. With some serious work, one could probably be soldered in. There's probably some other areas on the board that need modification too, much like Doobrey's PCMCIA access LED mod.
As for math operations, they're mostly relevant for things like rendering software and some processing libraries (mpega.library). Most recent programs take advantage of them. For a retro gaming Amiga setup, one probably isn't important.
