std.math.isNaN only works for floats. Is it safe to cast the 
double to float?

Why don't we have "isNaN(double)" (this is an honest question, to

The signature of the function shows it accepts a real:

pure nothrow  trusted bool isNaN(real x);

I am retarded. I had a compile error I miss-read, and was thrown 
of by "real" (not used to seeing it).

Thanks.
