in thread Looking for testers who use Microsoft compilers

Oh, thank you !!
That's helpful.

If you have any perls (the actual perl version is not important) built using earlier versions of a Microsoft Compiler, and those perls were also built with:
ivtype='__int64' ivsize=8
could you post the output of perl -V:ccversion for them ?

Somewhere between ccversion='16.00.30319.01' and ccversion='19.24.28316' a significant change in the MS C runtime occurred. (That change has relevance to List::Uniqnum.)
But I don't know exactly when that change occurred, and I'd like to find out.

Thanks again.

Cheers,
Rob

    Sorry, I only have installed Visual studio 2017 and 2019 on my server. most of time I've used strawberry perl.

      I only have installed Visual studio 2017 and 2019 on my server

      I was expecting that a perl built with Visual Studio 2017 would report a $Config{ccversion} that was less than '19.24.28316' and greater than '16.00.30319.01'. (My guess is that with Visual Studio 2017, $Config{ccversion} would begin with 19.1...)
      I thought that '19.24.28316' identifies Visual Studio 2019 and that '16.00.30319.01' identifies Visual Studio 2010.

      Anyway, if you have a perl (whose ivsize is 8) that has been built with that Visual Studio 2017 compiler, and could test List::Uniqnum that would be handy.
      Or, alternatively, just provide the output of perl -le "printf '%0.20g', 18446744073709549568;".
      That output will also tell me whether '%0.20g' formatting is reliable or not - and the thing I'm trying to work out is at which version of the Microsoft compilers did '%0.20g' become reliable.
      If it outputs 18446744073709549568, then '%0.20g' formatting is fine ... but not so if it outputs 18446744073709550000.
