https://issues.dlang.org/show_bug.cgi?id=23845 Issue ID: 23845 Summary: std.math.traits.copysign returns the wrong value Product: D Version: D2 Hardware: All OS: All Status: NEW Severity: major Priority: P1 Component: phobos Assignee: nobody puremagic.com Reporter: grylliade hotmail.com As written, the function simply returns its first parameter. Should likely return cast(R) *pto, though my pointer syntax is rusty—surely doing all that work with pto should have *some* point (no pun intended). I’d honestly bump this up to critical, but if no one’s noticed this yet, maybe it shouldn’t be—except copysign() can be called from cbrt(), at the very least. It keeps cbrt() from being inferred pure on the MS runtime, I think; if I’m wrong, that’s a separate bug. --
