Hi, This is the mailing list for libraries changes proposals. What's the library you're proposing a change to, and what is the change itself? In other words, let's say your proposal gets accepted — what's next? Roman * harry <voldermort@hotmail.com> [2013-06-16 00:26:05-0700]
The Enum instances for Float and Double have dubious semantics which cause endless confusion, e.g. http://stackoverflow.com/questions/13203471/the-math-behind-1-09999999999999..., http://stackoverflow.com/questions/9810002/floating-point-list-generator, http://stackoverflow.com/questions/7290438/haskell-ranges-and-floats, http://stackoverflow.com/questions/10328435/how-to-solve-floating-point-numb..., and many more.
I would therefore like to propose that the usage of an Enum instance of Float or Double generate a compiler warning, such as "The Enum instance of Float is subject to rounding errors". Deadline: 2 weeks.
Pedantic question: Should it be the Enum instance _of_ Float or _for_ Float?
