I'll look at it tonight.

Please try the bignum-fix branch.

[ohler55]

Release v1.17.2 with the fix.

Release v1.17.2 with the fix.

Thx Peter, This fix is really helpful to my work! And just have some confusion on "bignum-fix branch" when tried : the json is : { arr :[7.347709823877271e-05, 0.00010903867569251947]} pseudo code: 1) obj = oj.ParseString(json) 2) arr = JsonPath("$..arr").First(obj).([]any) 3) then range and check arr's element type using (e.g.) switch element.(type) the first element gives float64 (7.347709823877271e-05) the second gives json.Number (0.00010903867569251947)

can I detemine this json.Number is a float64, not a int64?

[ohler55]

Numbers are initially parsed as int64 or float64 until the number of digits exceeds the limits of each type and then the type reverts to json.Number. A json.Number is neither an int64 nor a float64. It can be convert to either but with a loss of precision if to a float64. If to an int64 and error is returned if the json.Number is out of range. Basically json.Number is a string that represents a number. It is up to the caller to decide what to do with it. That includes converting to int64, float64, or big numbers.

That's great guide on my case! Thank you so much!
