Hi Karlos
Just checked it last night in 68060 UM. They're hardware implemented. However what do these really do is rounding the result to single/double, regardless on the current FPU control setting, AND NOT making calculations in single/double. Calculations are always done in extended precision (or even more).
I've found SGLMUL, which makes calculations in single precision, but this is 6888x only and only emulated both on 68040 and 68060.
You can find all this in the manuals from that link to motorola site.
Good luck
