我不明白 [英] I don't understand

问题描述

这究竟是什么意思？

double percentdecrease =（Beginning Pop - Ending Pop）/ Beginning Pop

 

lblPercentDecrease.Text = percentdecrease.ToString（"P"）;   //对于百分比

 

解决方案

double percentdecrease =（Beginning Pop - Ending Pop）/ Beginning Pop

定义变量"percentdecrease" as  （Popning Pop - Ending Pop）/ Beginning Pop。

开始Pop，Ending Pop都是变量（Double integer）

所以如果开始Pop = 7并结束pop = 4然后百分比减少= 0.428571428

lblPercentDecrease.Text = percentdecrease.ToString（"P"）;  
//为百分比

文本框的标签"百分比减少"将是    0.428571428。

但百分比减少是一个整数，并且要将它放在文本框中，它必须首先是转换为字符串。

我希望这很清楚。如果没有让我知道或许我可以进一步混淆你：） < span style ="color：＃1f497d; font-family：Calibri，sans-serif; font-size：14.6667px">

What does this mean exactly?

double percentdecrease = (Beginning Pop – Ending Pop) / Beginning Pop

 

lblPercentDecrease.Text = percentdecrease.ToString("P");  // for percent

 

解决方案

double percentdecrease = (Beginning Pop – Ending Pop) / Beginning Pop

Defines the variable "percentdecrease" as  (Beginning Pop – Ending Pop) / Beginning Pop.

begining Pop, Ending Pop are all variables (Double integers)

so if Begining Pop = 7 and ending pop = 4 then percentdecrease = 0.428571428

lblPercentDecrease.Text = percentdecrease.ToString("P");  // for percent

the label for textbox "percentdecrease" will be  0.428571428.

However percentdecrease is an integer and to beable to place it within a textbox it must first be converted to a string.

I hope this is clear enough. If not let me know perhaps I can confuse you further :)
