BwB says
"Also, suppose Y and X are floating point variables, and M and B are
CONSTANT floating point variables (not named numbers) initialized to
1.0 and 0.0 respectively. If one writes
Y := M * X + B ;
can (and will) any compiler reduce this to
Y := X ;
Sure, this is just standard constant propagation, a very common
optimization.
