Hash float functions - request for help
Hello everyone, The hash functional tests have finally made it into the regression summary, but there are a few failures, mainly caused by the float functions. I've committed a couple of fixes that should improve matters, but I could use some help porting them to other compilers/platforms. I've attached a couple of test files, it would be great if you could run them on the compilers and platforms that you have access to and send me the results. It's quite likely that the second test will fail to compile, just let me know if it does. Send the results to me directly, to avoid noise. You'll need to add the boost include path when compiling the tests. The tests try to discover the versions of the float functions for the different float types - if you know of a differently named function for your platform that would be a great help. I guess the proper way to do this would be to add macros and tests to Boost.Config, but it's too near to the release to do that. thanks for any help, Daniel

Thank you, that's very helpful. The same version of Rogue Wave on Borland has completely different results - it seems this is as dependent on platfrom and compiler as library version. I've also used google to lookup similar info on Tru64, and it seems that only has long double functions on one platform. And gcc varies considerably, even on the same processor. Oh well. Also, thanks to Joaquín. Daniel
