Is there a plan to address this: floating-point implementations are subject to the vulnerabilities described in Casacuberta et al. "Widespread Underestimation of Sensitivity in Differentially Private Libraries and How to Fix it" (specifically the rounding, repeated rounding, and re-ordering attacks).

There is a workaround using fixed point. We did not come to a good solution as of now and there is more work required. Floating point arithmetic is tricky!
