This can be a test case, I didn't check it for 1.018, it works on 2.031.

[Issue 3162] New: can't fully use floats computed in CTFE as template parameters

pragma(msg, Format!(s=, cast(int)(1000*sqrt2))); // works
pragma(msg, Format!(s=, cast(int)(1000*sqrt2), , cast(int)(1000*sqrt2),

//pragma(msg, Format!(s=, cast(int)(1000*sqrt2))); // also doesn't work
pragma(msg, Format!(s=, cast(int)((1.0+sqrt2/2.0))); // doesn't works
Looks that only first occurence of value derived from constant derived using
ctfs can be used.
It was working in some older releases.

[Issue 2905] [PATCH] Faster +-*/ involving a floating-pointing literal
http://d.puremagic.com/issues/show_bug.cgi?id=2905
--- Comment #6 from Don clugd...@yahoo.com.au 2009-07-10 07:37:23 PDT ---
Revised patch against DMD2.031, which fixes the problem, and optimises a larger
number of cases. This patch significantly improves performance of
floating-point operations involving reals.

Additionally if i omit double in static const double, it compiles! It is
the same type!
I was also testing this ctfe function
T i(T)(T x) {
return x;
}
and only with T=float,double,real i got errors.
