+// The code in this module is derived from the `lexical` crate by @Alexhuszagh
+// which the author condensed into this minimal subset for use in serde_json.
+// For the serde_json use case we care more about reliably round tripping all
+// possible floating point values than about parsing any arbitrarily long string
+// of digits with perfect accuracy, as the latter would take a high cost in
+// compile time and performance.
+//
+// Dual licensed as MIT and Apache 2.0 just like the rest of serde_json, but
+// copyright Alexander Huszagh.
+
+//! Fast, minimal float-parsing algorithm.
