 Float literals with zero fractional part can be safely replaced with integer literals.
 For example, it is safe to write `1.3 * 42` instead of `1.3 * 42.0`.
 
-Floats can also include the same underscore separater as integers. For example, `1_000.4_400` is a float whose value is equivalent to `1000.4400`.
+Floats can also include the same underscore separator as integers. For example, `1_000.4_400` is a float whose value is equivalent to `1000.4400`.
 
 TIP: As integers are more convenient to use than floats with zero fractional part, we recommend to require `x: Number` instead of `x: Float` in type annotations.
