  normalisation
       
          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}.
