Description Atsushi Eno 2014-01-30 02:55:54 UTC
From http://d.hatena.ne.jp/hnw/20140129

double d = Double.MaxValue;
Console.WriteLine(d); // 1.79769313486232E+308
Console.WriteLine(Math.Round(d, 1)); // Infinity

.NET prints 1.79769313486232E+308 but I'm not sure if it is correct.

I cannot reproduce with Mono (master/117468d740a). I get the same behavior as on .NET on Windows.
