PH30400: z/OS Connect EE incorrectly transforms some numbers with a lot of digits after the decimal point.

APAR status

• Closed as unreproducible in next release.

Error description

• When an API requester program attempts to receive a high
  precision floating point value such as 234567891234.5678901234,
  the transformed value is not valid.
  
  The field is defined in the Swagger document as
  "format":"decimal". The COBOL structure generated was type
  S9(28)V(3), the required type is S9(13)V9(10).

Problem summary

• ****************************************************************
  * USERS AFFECTED: All users of z/OS Connect EE V3.0 API        *
  *                 requesters.                                  *

  * PROBLEM DESCRIPTION: z/OS Connect EE incorrectly transforms  *
  *                      some numbers with many digits after the *
  *                      decimal point.                          *
  ****************************************************************
  The translation of numbers between the API requester payload and
  JSON number format resulted in incorrect values being used. This
  was because values with a lot of numbers after the decimal
  point were not translated correctly.
  
  It was not possible to control the number of digits after the
  decimal point because the z/OS Connect EE build toolkit always
  specified that the number of fraction digits was 3.
  

Problem conclusion

Temporary fix

Comments

• The z/OS Connect EE API requester code has been updated to
  correctly translate decimal numbers with a large number of
  digits after the decimal point.
  
  The build toolkit has also been updated to allow
  defaultFractionDigits to be specified in the properties file.
  The defaultFractionDigits parameter description is:
  "Specify the default number of fraction digits to use on a JSON
  decimal schema type. For COBOL, the valid range is 0-17, or 0-30
  if parameter wideComp3 is being used. For PLI, the valid range
  is 0-30.
  The default value is 3."
  
  The fix for this APAR is expected to be delivered by the PTF for
  z/OS Connect EE V3.0.43.0 (PH34379).
