This is about software emulated FP. OFC NetBSD used the FP module in CPU's since long ago. Also, FP is not math, it's just a kind of math. And even Forth users will use a fixed point before going into float. With 32 bits, they will just scale the point and call it a day. And seasoned Forth users will just use quotient arithmetic and output fractional parts as two items in the stack.
