Problem summary

• ****************************************************************
  * USERS AFFECTED: Users of Enterprise COBOL 6.3 compiling and  *
  *                 running programs compiled with the           *
  *                 ARITH(EXTEND) option in effect and where     *
  *                 the program contains an intrinsic function   *
  *                 invocation with an argument that is a        *
  *                 numeric expression containing at least one   *
  *                 COMP-2 operand.                              *
  ****************************************************************
  * PROBLEM DESCRIPTION: A loss of accuracy in the result of the *
  *                      intrinsic function computation.         *
  ****************************************************************
  * RECOMMENDATION: Apply the provided PTF.                      *
  ****************************************************************
  The code generated by the compiler for the intrinsic function
  computation was inadvertently truncating the 128-bit
  intermediate floating point result of the argument expression
  to a 64-bit floating point value.
  

Problem conclusion

• The compiler was updated to avoid truncating the numeric
  expression result to a 64-bit floating point value when
