normalisation
normalised
unnormalised

   1.  A transformation applied uniformly to
   each element in a set of data so that the set has some
   specific statistical property.  For example, monthly
   measurements of the rainfall in London might be normalised by
   dividing each one by the total for the year to give a profile
   of rainfall throughout the year.

   2.  Representation of a floating-point number
   so that its mantissa's left-most digit is non-zero.  If the
   leftmost fraction digit are zeros, the number is said to be
   unnormalised.  Unnormalised numbers are normalised by shifting
   the fraction left, one digit at a time, until the leftmost
   digit is nonzero and reducing the exponent by the number of
   shifts.

   3.  database normalisation.
