Why is it in std.numeric anyway? I would expect std.numeric to 
contain numerical algorithms, not something like this.

Suggestion: Combine HalfFloat with CustomFloat and move the 
result in a separate module, say std.float. Also move there 
IeeeFlags, FloatingPointControl, NaN, getNaNPayload, nextUp, 
nextDown, nextafter and related things. Those have nothing to do 
with math. Possibly also isNaN, isFinite, isNormal, isSubnormal 
and isInfinity.
