微控制器具有较强的加、减、乘、除等数学运算功能，这些运算可直接对8位无符号二进制数进行运算。利用溢出标志，还可以把加、减法运算用于有符号数的运算；用十进制调整指令，又可使加法运算直接用十进制（BCD码）来进行。-Micro-controller has strong add, subtract, multiply, divide and other math functions, these operations can be directly on the 8-bit unsigned bin

用于四轴飞行器的姿态算法，内含各种矩阵加减乘转置、求逆等运算，及姿态kalman滤波算法，可适用于低速旋翼机的姿态导航-For four-axis spacecraft attitude algorithm, containing a variety of matrix addition and subtraction to multiply the transpose and inverse operations, and attitude Kalman filtering algorithm
