+When checking the type of union type, ignore the `nil` in it.

+When this setting is `false`, the `number|nil` type cannot be assigned to the `number` type. It can be with `true`.

 Once one subtype of a union type meets the condition, the union type also meets the condition.

+对联合类型进行类型检查时，忽略其中的 `nil`。
+
+此设置为 `false` 时，`numer|nil` 类型无法赋给 `number` 类型；为 `true` 是则可以。
