      The following is a major/minor bug which maybe/may not be trivial.

Try assigning a "float" variable to a "double" variable - results in a
loss of accuracy with the magnitude being greater for larger numbers. A
"promotion" should result in better accuracy and not viceversa. A simple
rogram was tested on the Microsoft Ver 6 compiler and also the watcom
386 compiler. The problem started off as trivial but still hasn't been
solved.             

                     
      
       See if you any of you guys out there can do it.

n a better accuracy
