-      - `int` (type: *bool*, default: *true*): parse digits into integer (value consists of only numbers).
-      - `float` (type: *bool*, default: *true*): parse decimals into integer (value consists of only numbers with decimal point).
-      - `bool` (type: *bool*, default: *true*): parse if string equals to *'true'* or *'false'*.
