     1. <data processing> 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. <programming> 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> database normalisation.
