Do you propose to write/port pure Java implementations for those?

No, it is outdated (merged into "master").

Sure.
Functionality should go in module "commons-math-legacy-core"
(where "FastMath" was moved and renamed "AccurateMath").
Note that the "legacy" specifier refers to codes that depend on other
legacy codes ("legacy-core" still depends on "legacy-exception").
[Of course you are welcome to provide a fully refactored module.]

Gilles

I should base it on the modularized_master branch, I take it?
