The updated docs for std.math explicitly refer to exception flags and
rounding modes. (eg FE_TONEAREST in rndtonl(real  x) ).

Does this mean there's been some thought about how this will work?
Currently this is arguably the very worst part of the documentation
at present:

----------------
float.html
----------------
IEEE 754 floating point arithmetic includes the ability to set 4 different rounding modes. D adds syntax to access them: [blah, blah, blah] [NOTE: this is perhaps better done with a standard library call]

Exception Flags
IEEE 754 floating point arithmetic can set several flags based on what happened with a computation: [blah, blah, blah]. These flags can be set/reset with the syntax: [blah, blah, blah] [NOTE: this is perhaps better done with a standard library call]
---------------

Will it be a library call, or done with properties?

I would also like access to the precision control. It could be used to verify that code for reals will continue to function correctly with 64-bit reals as well as 80-bits (it would also allow some direct accuracy comparisons to demonstrate the merit of extended reals).

I don't know yet, haven't really thought about it. What do you think?
