Function normalizeJSONNumber

stores/json/store.go:139–152

normalizeJSONNumber converts a json.Number scalar (produced because the decoder runs with UseNumber) into an int for integers within the int64 range and a float64 otherwise. Non-number tokens are returned unchanged; a number representable as neither returns the json.Number.Float64 error.

(t interface{})

// and a float64 otherwise. Non-number tokens are returned unchanged; a number
// representable as neither returns the json.Number.Float64 error.
