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.
