编译器警告在printf(）中使用float而不是double

如果我给出浮点值而不是双精度，我会收到警告。这就是为什么我使用static_casts来加倍。如果我决定不进行强制转换，有没有办法避免编译器警告？为什么存在此警告？在我的系统（8位处理器）中，我怀疑double是否和float大小相同。

             printf("{"type":"pid_cnf","
                    ""pit_rkp":%.2f,"pit_rki":%.2f,"pit_rimax":%.2f,"
                    ""rol_rkp":%.2f,"rol_rki":%.2f,"rol_rimax":%.2f,"
                    ""yaw_rkp":%.2f,"yaw_rki":%.2f,"yaw_rimax":%.2f,"
                    ""pit_skp":%.2f,"rol_skp":%.2f,"yaw_skp":%.2f}n",
                    static_cast<double>(pit_rkp), static_cast<double>(pit_rki), static_cast<double>(pit_rimax),
                    static_cast<double>(rol_rkp), static_cast<double>(rol_rki), static_cast<double>(rol_rimax),
                    static_cast<double>(yaw_rkp), static_cast<double>(yaw_rki), static_cast<double>(yaw_rimax),
                    static_cast<double>(pit_skp), static_cast<double>(rol_skp), static_cast<double>(yaw_skp) );
