    j := gojsonq.New().JSONString(text).Find("id")
    fmt.Println("Num: ", j, "\nType: ", fmt.Sprintf("%T", j))

This package decode the JSON document in map[string]interface{}, JSON number is decoded in float64 https://github.com/golang/go/blob/master/src/encoding/json/decode.go#L53

You can do it like,

func main() {
    text := `{"id": 1827049}`
    j := gojsonq.New().JSONString(text).Find("id")
    fmt.Println("Num: ", j, "\nValue: ", fmt.Sprintf("%d", uint64(j.(float64))))
}

Output:

Num:  1.827049e+06
Value:  1827049
