http://d.puremagic.com/issues/show_bug.cgi?id=11135 Summary: Nullable(T, T nullValue) does not support NaN Product: D Version: D2 Platform: x86 OS/Version: Windows Status: NEW Keywords: patch Severity: normal Priority: P2 Component: Phobos AssignedTo: nobody puremagic.com ReportedBy: anoneuron gmail.com A little unsurprising, but quite annoying. See this simple test case: void main() { import std.stdio; import std.typecons; Nullable!(float, float.nan) Value; writeln(Value.isNull, " <- should be true"); Value.nullify(); writeln(Value.isNull, " <- should be true"); }; Value.isNull always evaluates to false. A simple patch in typecons.d seems to resolve the issue, in the isNull function on line 1478, replace return _value == nullValue; with return _value is nullValue; I don't *think* this change could cause other issues, but I'm not completely certain. Tested using DMD v2.063.2 on WinXP. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
