Note that this can be ambiguous. It is not unknown for, say, a double
precision variable in a register to be faster than a real in a register
(e.g., the machine may do all operations in double precision so the real has
the extra overhead of conversion to and from double precision), but the
slower data transfer rate for double precision makes operations on double
precision variables in main memory slower than operation on reals in main
memory.
