Proposing this is fine. But doing a fully custom implementation that includes this? You're going to implement sin and cos and atan for 128-bit decimals? When we could use an open source library that has a compatible license instead and is proven to work for these already instead, likely with better performance as well? This is likely to be more work than doing a type backed by a library while also being less capable. I know that your shift in proposal here is not aimed at me, and also I'm not a voter so in that sense it doesn't matter. But if this is what the proposal ends up being, I'll probably just continue on the research for an actual arbitrary precision implementation based on MPFR instead of helping with this implementation.
