Its just that Jiffy (CouchDB's JSON parser) is capable of handling bignums easily since Erlang has bignum support built in. This works by detecting when it successfully parses a number (i.e., we found a string that matches JSON grammar) but isn't capable of storing the value in a native type. When that happens, we set a flag and wrap the sub-binary with a tagged tuple that is then processed in Erlang. The logic in C can be found here: https://github.com/davisp/jiffy/blob/9ea1b35b6e60ba21dfd4adbd18e7916a831fd7d4/c_src/decoder.c#L588-L617 And then when the parsed JSON value is passed back to Erlang we run this function over it to get real bignums: https://github.com/davisp/jiffy/blob/master/src/jiffy.erl#L111-L142 That said, if you're working with large numbers you'll want to either ensure that your JSON parser has bignum support, or follow @nickva's advice and store your numbers as strings to be interpreted at the application level. -- This is an automated message from the Apache Git Service.
