math/big: big.Rat has not Marshall/Unmarshall methods #7287
Description
by skurtsev:
It seems that no Marshal/Unmarshal methods available for big.Rat whilst big.Int has proper methods. E.g. marshaling big.Rat inside struct results in empty value for big.Rat fields: see INVALID_RAT in json output at http://play.golang.org/p/M_IgJUGSpo What steps will reproduce the problem? 1. Create big.Rat var inside another struct 2. Call json.Marshall for the struct 3. What is the expected output? big.Rat must be serialized to json (unserialized from json) What do you see instead? Empty {} instead of big.Rat's serialized value Which operating system are you using? Linux localhost 3.12.9-301.fc20.i686+PAE #1 SMP Wed Jan 29 16:12:24 UTC 2014 i686 i686 i386 GNU/Linux Which version are you using? (run 'go version') go version go1.2 linux/386 Please provide any additional information below.
