[svn-r7868] Purpose: new feature

Description:  data type conversion between integers and float numbers.
              (Cover your ears.  It's going to explode.:)

Solution:       covers all native type conversion.  Mainly uses hardware
            conversion but handles overflow more gracefully.

Platforms tested: h5committest
