...and A=1:B=1 is faster than A=1.00000000:B=1.00000000   :-)

Btw whether B=A is faster than B=1 may depend on how many variables your
program has.  The "=A" require a lookup of the variable A.  IF your program
has few variables (as small test programs tend to have), B=A is definitely
faster than B=1.  But if your program has a large number of variables,
then B=A may be slower, depending on where in the list of variables A
happens to reside.
