Bug 3202 basically says that std.math.pow(someFloat, int.min) enters an
infinite loop because int.min == -int.min. Here's my suggestion for a
fix:
--- std/math.d (revision 1672)
+++ std/math.d (working copy)
@@ -2904,6 +2904,12 @@
return 1 / x;
case -2:
return 1 / (x * x);
+ static if (isSigned!G)
+ {
+ case G.min:
+ enum absGmin = cast(Unsigned!G)(-(G.min+1)) + 1;
+ return 1 / pow(x, absGmin);
+ }
default:
}
I'm wary of doing anything to std.math, since it's so fundamental and
performance-critical. So please, speak up if you see a problem with
this patch.
