+A binary operation was attempted on a type which doesn't support it.
+Erroneous code example:
+
+```
+let x = 12f32; // error: binary operation `<<` cannot be applied to
+               //        type `f32`
+
+x << 2;
+```
+
+To fix this error, please check this type implements this binary operation.
+Example:
+
+```
+let x = 12u32; // the `u32` type does implement it:
+               // https://doc.rust-lang.org/stable/std/ops/trait.Shl.html
+
+x << 2; // ok!
