Description of Problem
----------------------
An implicit conversion of an operand of type universal_real to another
floating-point type can only be applied if the operand is either a numeric
literal, or an attribute name. Thus,  the expression  "4.0 / 2"  is never
implicitly converted to a real.


Proposed Resolution
-------------------
An implicit conversion to a floating-point(integer) type may always be applied
to an operand of type universal_real (universal_integer).
