+### Double
+
+The `Double` Converter converts an inputted `value` into a double.
+
+The returned type is float64.
+
+The input `value` types:
+* float64. returns the `value` without changes.
+* string. Tries to parse a double from string. If it fails then nil will be returned.
+* bool. If `value` is true, then the function will return 1 otherwise 0.
+* int64. The function converts the integer to a double.
+
+If `value` is another type or parsing failed nil is always returned.
+
+The `value` is either a path expression to a telemetry field to retrieve or a literal.
+
+Examples:
+
+- `Double(attributes["http.status_code"])`
+
+
+- `Double("2.0")`
+
 ### Duration
 
 `Duration(duration)`
