我为RA6M5编写程序，在程序中使用了sin(x)函数，但是无论我怎么努力都无法使用
情况一、
使用sin函数得到'sin' has unknown return type; cast the call to its declared return type的错误。但是程序可以顺利编译和执行。
相关代码如下：

R_BSP_SoftwareDelay(delay, bsp_delay_units);
}
}
但是，cyclePien的数值是正确的。（下面会说）
程序无法正确执行。
情况二、
使用keil进行编译，则非常离谱，cyclePien的变量居然是错误的，而且无论怎么定义，都不可以。cycle始终为0，cycle==0；

而我即时修改了，相关的配置也不可以。无论怎么修改都不正确！
太过邪门，请大家解惑！！！
