Compare two PRBMath.UD60x18 values directly (without converting or .value)?

Do the PRBTest assertions support checking equality between two PRBMath.UD60x18 values directly (without converting or doing .value)?

[PaulRBerg]

This is a very good question!

PRBTest doesn't support the PRBMath variable types, and it will likely never support them. The reason for that is that I intend to test PRBMath v3 with PRBTest itself, and so if PRBTest also imported PRBMath to provide assertions for its types, there would be a circular import.

What I plan on doing, once I get to implementing PRBMath v3, is to offer assertEq assertions for SD59x18 and UD60x18 (see the staging branch) directly from the prb-math repository. There would be a test directory, which you would import something like this:

import { PRBMathAssertions } from "@prb/math/test/Assertions.sol";

Update: I shipped PRBMath v3 in the meantime, which comes with testing assertions for SD59x18 and UD60x18. Check them out here:
