Subject: [boost] iround() and itrunc() in Conceptual Requirements for Real Number Types

Regarding the page Conceptual Requirements for Real Number Types
Is it still accurate to list these 2 rows under Standard Library Support
- iround(cr1) | int
- itrunc(cr1) | int
The motivation in asking this is two-fold:
1. I don't see either of these functions listed in the Standard Library.
Perhaps this is just old documentation, or I am not looking in the right
place. Instead, I do find lround() and truncl().
2. One of the design goals of Boost.Autodiff (WIP) is to satisfy all of
the requirements on this page, and these are the only two which I am unable
to satisfy for the above reason.
If someone were to update this page, or otherwise advise on how to
reconcile, it would be appreciated so that the Boost.Autodiff
<https://github.com/pulver/autodiff> library could accurately claim to
satisfy 100% of Boost's Real Number Type requirements.
