>V4R4.

      Eval(H)    CubeRoot = Value ** (1/3)

Note that use of ** causes the result to be a floating point number, so it is
best to use (H) half-adujst on the Eval if the result field (CubeRoot) is not
also a float field.  If you want the above to be part of another expression, you
can force the conversion from float back to packed decimal as part of the
operation as in:

     Eval      Result = FieldA * ( %DECH( Value ** (1/3): 15: 5 ) + FieldB )
