Auf der Suche nach Komponententestdaten für Block.Bits zu und von einer JSON-RPC-Zeichenfolge

Ich versuche, das JSON-RPC-Ergebnis der komprimierten Bits-Eigenschaft eines Blocks mit der folgenden Einschränkung in ein C#-Float zu konvertieren

 //3  bytes mantissa, the leading byte as exponent (where only the 5 lowest bits are used) and its base is 256

Gibt es Beispieldaten, mit denen ich überprüfen kann, ob meine Implementierung funktioniert?

Ein JSON-RPC-String und die entsprechende 256-Bit-Ausgabe im Big-Endian-Format wären eine große Hilfe.
