当我使用UARTprintf()打印输出一个int型变量时，是OK的，但该函数不支持浮点变量。
请问该如何打印输出一个浮点变量呢？
float Xangle,temp;
temp = Xangle;
printf("\r\n");
if(Xangle>=0){ printf("radX:%d.%d",(int32_t)temp ,(int32_t)((temp -(int32_t)temp )*1000));
}
else{
temp = 0-temp;
printf("radX:-%d.%d",(int32_t)temp ,(int32_t)((temp -(int32_t)temp )*1000));
这个只能智取了
