Message        <Context> "<expression>" has more precision than
               "<target type>".  Assignment might result in loss of
               precision and/or range.

Description    The destination of a floating-point assignment has
               less range and/or precision than the expression being
               assigned to the destination.  Because of this, the
               assignment might cause a loss of range and/or
               precision.

User Action    Verify that no unexpected data can be lost by the
               assignment.  If not, cast the expression to the type
               of the destination.
