I'm not sure I can sign up for ALL of std.math. I'm sure I'll need help. I can do roots, powers and transcendental functions, though. Maybe not very efficiently (power series).
It's not necessary to come out of the starting gate with them all implemented to arbitrary precision. A workable first version can just call the std.math real versions, and note in the documentation as a bug that the precision is limited to real precision.
The various constants, like std.math.E and PI should also be there. They can be lazily evaluated.
I also suggest that the type be a template parameterized with the exponent bits and mantissa bits. float, double and real would then be specializations of them.
(If very high precision numbers are questionable, how valuable are high precision sine and cosine??)
If one accepts the utility of high precision numbers, then one must also accept the utility of high precision math functions!
