I think formatting cannot be done such that it is CTFE-able. I tried implementing a less-inefficient version. As far as I can tell at some point you need to extract the significand and the exponent. This is done by some "unsafe" cast which is not allowed in CTFE. I don't know a way to do it in CTFE-compatible way. Jens
