Actually it does... Under the IBM suboption:
- Nonzero scale factors are permitted in FIXED BIN declarations. - If the result of any precision-handling built-in function (ADD, BINARY, and so on) has FIXED BIN attributes, the specified or implied scale factor can be nonzero. Under the ANS suboption: - Nonzero scale factors are not permitted in FIXED BIN declares. - If the result of any precision-handling built-in function (ADD, BINARY, and so on) has FIXED BIN attributes, the specified or implied scale factor must be zero. https://www.ibm.com/support/knowledgecenter/SSZHNR_2.0.0/com.ibm.ent.pl1.zos.doc/pg/rules.html Joe On Mon, Sep 7, 2020 at 12:23 AM Robin Vowels <robi...@dodo.com.au> wrote: > On 2020-09-07 13:05, Joe Monk wrote: > > "No it isn't. 4/3 yields 1.333333... to 15 digits, > > and is of precision (15,14)" > > > > Depends on RULES(IBM) or RULES(ANS).
