https://keymaterial.net/2026/05/13/so-you-want-to-deploy-fn-... talks about FN-DSA and has a section about how it's require to hand-implement floats to get constant-time operations.
That and not be at the mercy of someone changing the current rounding mode behind your back.
Also hand-implement floats ... not likely to be particularly efficient, no ?
I took a quick glance at the section "About those floating points". Whomever designed that algorithm used the biggest footgun ever. I mean floating point numbers? For crypto?
Even if he can mathematically prove is algorithm is solid, he's going to lose 99% of his intended audience the moment he's going to use the words crypto and floating point in the same sentence.
