+error[E0277]: the trait bound `f64: Eq` is not satisfied

+   |           ^^^^^^^^^^^ the trait `Eq` is not implemented for `f64`
+   |
+   = help: the following other types implement trait `Eq`:

+             i16
+             i32

+             u128
+             u16
+           and 4 others
+   = note: required for `Option<f64>` to implement `Eq`
+note: required by a bound in `AssertParamIsEq`
+  --> $SRC_DIR/core/src/cmp.rs:LL:COL
+   = note: this error originates in the derive macro `Eq` (in Nightly builds, run with -Z macro-backtrace for more info)
