Hi Jorg, On 13.01.24 00:25, Jorg Sowa wrote:
Thank you for the suggestions. I agree that error message should be more meaningful. I changed it. The main driver of this change is to match the division by zero behavior for both operators which can operate on both integers and floats. Would it make sense to create a function fpow similarly to fdiv for the correct IEEE 754 logic?
As of your note of consistent behavior here, in your RFC I don't see any note about operating on float - It's all about int. It would be good to explicitly describe both int and float behavior in your RFC. About fpow - I personally never felled the need to use fdiv but as fdiv was explicitly introduced to expose IEEE-754 semantics I think it totally makes sense to add fpow as well. Greetings, Marc
Kind regards, Jorg
