比较2个双精度变量和2个小数 [英] Comparing 2 double variables withing 2 decimals

问题描述

问候，

作为编程的返回者(上次使用Borland Pascal 5.5时是90年代，别再笑了)，我想知道比较2位小数内的2个数字最方便的方法.

由于数据的来源是字符串(gps提要)，因此我正在考虑做 Convert.ToDouble(sVar )，但不确定如何在此处实现字符串格式.

很长的路要走，就是搜索小数点，然后将接下来的2个数字放在单个字符串中，然后进行 convert.ToInt 进行比较，但是如果可能的话，则需要更少的代码和脑力消耗

任何想法都会受到欢迎，因为如果可以将这部分软件放到这里，这将是我的重返项目.


谢谢，

BBB

Greetings,

As a returnee to programming (last time in the 90''s with Borland Pascal 5.5, stop laughing) I want to know the handiest way of comparing 2 numbers within 2 decimals.

As the origin of the data is a string (gps feed), I''m thinking along the line doing a Convert.ToDouble(sVar but not sure how to Implement string formats here.

The long way would be to search for the decimal point and then place the next 2 numbers in a single string and convert.ToInt and compare then but if possible want something a bit less code and brainpower consuming

Any Idea''s welcome as this is my back to work project if I can pull this bit of software off.


Thanks,

BBB
