arithmetic external的意思|示意

Remember, integer arithmetic is much faster than floating-point arithmetic, as it can usually be done directly by the processor, rather than relying on external FPUs or floating point math libraries.

记住，整形数运算要比浮点数运算快得多，因为处理器可以直接进行整型数运算，浮点数运算需要依赖于外部的浮点数处理器或者浮点数数学库。

The double steps external characteristic of the welding rectifier is realized by closed loop feedback and PID arithmetic.

通过闭环反馈及PID算法实现了焊机的双阶梯形外特性。

A microprocessor executes encoded instructions to perform arithmetic operations, internal data transfer, and communications with external devices.

微处理器执行代码指令进行算术运算，内部数据的传递以及与外部设备通信。
