    Description

      A DESCRIPTION OF THE PROBLEM :
      The description for Math.ulp(float/double) and StrictMath.ulp(float/double) doesn't tell us what ulp stands for, i.e. "unit in the last place".
      This is not a big deal, and the information is in fact available in the description of the Math class (though it's not even mentioned elsewhere in StrictMath), but it represents a slight inconsistency with the description of BigDecimal.ulp(), which does tell us what it stands for.

      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      Returns the size of an ulp, a unit in the last place, of the argument.
      ACTUAL -
      Returns the size of an ulp of the argument.
