Re: [go-nuts] Generic constant type parameters?

Hmm, I thought I had it “working” using this code https://go.dev/play/p/pzKacmi3aPe but there is a compiler error, but according to the accepted proposal documentation this should be valid https://go.googlesource.com/proposal/+/refs/heads/master/design/43651-

Re: [go-nuts] Re: Generic constant type parameters?

Obviously one way to do it is to copy and paste the code and/or generate under different type or package with different decimal place values. On Oct 15, 2024, at 10:53 PM, Robert Engels wrote:Not really. The idea is that use multiple types with different number of decimal places. Eg. 7 for interm

Re: [go-nuts] Re: Generic constant type parameters?

Not really. The idea is that use multiple types with different number of decimal places. Eg. 7 for intermediate operations and 2 for summary values, etc. Thanks for trying to help though. On Oct 15, 2024, at 10:35 PM, Cleberson Pedreira Pauluci wrote:Hi, Robert.I'm sorry. Now I got it.But I think

Re: [go-nuts] Re: Generic constant type parameters?

Hi, Robert. I'm sorry. Now I got it. But I think what you are trying to do is not possible in Go yet. @Ian already answered about this. Have you thought of another way to do this? Maybe reading the "nPlaces" value from something like a configuration file and storing it as an encapsulated field

Re: [go-nuts] Re: Generic constant type parameters?

I think you misunderstood the question or it wasn’t clear. The struct can only contain a single int64 - so you cannot add another value to hold the number of decimal places. The idea is to track the number of decimal places via the type (or method on the type) so the compiler knows it while generat

[go-nuts] Re: Generic constant type parameters?

Hi. Maybe you can use encapsulation instead of standalone function and generics. Encapsulation is a fundamental principle in software engineering. It controls which parts of a package are visible from the outside and which are not. It hides implementation details, allowing changes that do not af

[go-nuts] Generic constant type parameters?

Hi, Is there someway of doing this with Go generics? https://github.com/robaho/cpp_fixed/blob/6770b217acd84e4b723449e4c4bb42c92e7f2af1/fixed.h#L18-L23 I could make the type and interface and add a method for ‘decimal places’, but I would like all of the constants to be resolved at compile time.
