  • 



Problem summary


    

  • When using JZOS IbmDoubleField to convert an IEEE floating point
value into an IBM hexadecimal floating point value, if the IEEE
value is too close to zero to be represented in IBM hexadecimal
format, an incorrect result is returned.

    



Problem conclusion


    

  • This defect will be fixed in:
7.0.0 SR6 (z/OS 64-bit)
.
The JZOS IbmDoubleField class has been updated such that
converting an IEEE floating point value into an IBM hexadecimal
floating point value will return correct results. For values
that are too close to zero to be represented in the equivalent
IBM hexadecimal format, zero will be returned.
