So what about what I said is inaccurate?  ISTR that at least the 
2-operand form allows you to work with two 32-bit floats, which 
are equivalent in precision to the floats that are used with, for 
example, colours.  And overriding the colour functions, such as 
adding, scaling, and inverse-scaling colours, might not be such 
a difficult task.  However, again, I don't think one would gain 
much for one's labour.
