一种用VHDL语言描述的浮点平方根前规格化的源代码编程-VHDL language used to describe a floating-point square root of the source code before the standardized programming

笔算开方，利用长除法求浮点数的平方根，有优点是迭代次数少，缺点：只能算到小数点后4-5位-4-5 can only count to one decimal: written calculation prescribing, use long division square root of floating-point number has the advantage of fewer iterations, shortcomings
