     22 -- This file tests base conversions from string to a decimal number
     23 -- and back to a string (in Scientific form)
     24 
     25 -- Note that unlike other operations the operand is subject to rounding
     26 -- to conform to emax and precision settings (that is, numbers will
     27 -- conform to rules and exponent will be in permitted range).  The
     28 -- 'left hand side', therefore, may have numbers that cannot be
     29 -- represented in a decDouble.  Some testcases go to the limit of the
     30 -- next-wider format, and hence these testcases may also be used to
     31 -- test narrowing and widening operations.
