can Quartus 18.1 synthesize real number?

Hi,

Many people told me that FPGA cannot synthesize real numbers but I try real number on Quartus 18.1 Pro on Arria10 and it works. At the same time, i cannot find official document from Intel to clarify this. Any idea if 18.1 can officially synthesize real number? any exception at all?

Thanks

By "real" do you mean a single precision floating point number?
