 ## Main limitations
 
-- Doesn't work with `no_std` (for now)
-- Doesn't fix the floating point quirks such as `0.0 == -0.0` (because that would introduce a runtime overhead)
+- Doesn't fix the floating point quirks such as `0.0 == -0.0`
+- Doesn't fix the odd methods such as:
+  - `sqrt(-0.0)` returning `-0.0` instead of `NaN`
+  - `min(-0.0, 0.0)` returning `-0.0` instead of `0.0` (same for `max`)
+  - `frac(-0.0)` returning `0.0` instead of `-0.0`
+
+Because that would introduce a runtime overhead and may introduce some incompatibilities with existing code.
