Calculating Absent Time Problem

Hey all

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

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  

    //TotalEmployeeTargetHours.Ticks = 4995000000<code>000 

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


    AbsentPercentage = ValC;
}   

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

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