摘要
根据子午线弧长计算公式,推导出基于递归关系的任意精度的子午线弧长的一种新的计算方法,以及基于C/C++语言的子午线弧长具体方法的实现,最后在VC6.0中进行了验证。结果表明,该方法可满足不同精度要求的弧长计算。
A new method for recursive computation of meridian arc length with discretionary precision is deduced on the basis of the arc formula, and its detailed algorithm as well as program in C/C + + are given. This method for arc length computation is proved through Microsoft VC + + 6.0, the result indicates that different precisions requirement in various conditions can be met with.
