计算缺席时间问题 [英] Calculating Absent Time Problem

问题描述

嘿

我有两个TimeSpan变量. HoursWorked 和TargetHours.

I''ve got Two TimeSpan variables. HoursWorked and TargetHours.

现在，我需要计算缺席时间的百分比.所以这是代码:

Now what I need is to calculate the percentage of absent time. So here''s the code:

 

float AbsentPercentage = 0;

if (TotalEmployeeTargetHours.Ticks != 0)
{

   float ValA = (TotalEmployeeHoursWorked.Ticks / TotalEmployeeTargetHours.Ticks);

      // TotalEmployeeHoursWorked.Ticks  = 5073600000000  

      // TotalEmployeeHoursWorked.Ticks  = 5073600000000  

     //TotalEmployeeTargetHours.Ticks = 4995000000 <code>00 0 

    //TotalEmployeeTargetHours.Ticks = 4995000000<code>000 

    float ValB = ValA * 100;
    float ValC = 100 - ValB;


    AbsentPercentage = ValC;
}   

    float ValB = ValA * 100;
    float ValC = 100 - ValB;


    AbsentPercentage = ValC;
}   

应该可以，对吧? ValA总是被分配0或1.所以我的缺席百分比始终是100％或0％

That should work, right? ValA ALWAYS gets assigned either 0 or 1. So my absent percentage is always 100% or 0%

 

我先尝试使用小数然后尝试了浮点数，我认为可能会在后台发生某种类型的转换... 

I tried using decimal first and then tried floats, i thought there might be some kind of cast happening in the background... 

 

 

推荐答案

ValA * 100;

ValA * 100;

 

刻度不是浮点数.您需要将TotalEmployeeTargetHours.Ticks强制转换为浮点数，以获取浮点结果.否则，它会向上或向下取整，然后将THEN分配给浮点值.

Ticks is not a float.  You need to cast TotalEmployeeTargetHours.Ticks to float, to get a floating point result.  Otherwise it gets rounded up or down, and THEN gets assigned to the floating point value.
