Thanks, but I outsmarted myself. I shoudl have asked for what I really wanted.
If I do that, it works just fine. If I try to use a constant ABOVE 1.0, then it only uses the fractional portion, so
const0 = (1.2, 1.2, 1.2, 1.0)
results in my multiply being .2, .2, .2, 1.0.
Do you know any way around this? We've tried multiplying by the fraction, and scale_by_two(), but can't seem to get the syntax right.
