In engineering-notation the exponent is always an integer multiple of
3.  SCM scales the matissa to be between 1 and 1000, and omits the
exponent when it is 0.

Engineering-notation is good for viewing floating-point numerical
data.  Unless the data is very erratic, one can tell from looking at
the mantissas when the exponents have changed.
