Question

Hello All,

 

   Here I Have one Formula  i want to find a logic for this through c# code

 

T_negative = T_0 + (T_Filtertime - 10ms)       for T_Filtertime <= 100ms

T_negative = T_0 + (T_Filtertime * 0.9) for      T_Filtertime > 100ms

T_negative = T_0 + (T_Filtertime - 5000ms)     for T_Filtertime >= 50000ms

 

T_positive = T_0 + (T_Filtertime + 10ms) + (20ms + 10ms)    for T_Filtertime <= 100ms

T_positive = T_0 + (T_Filtertime * 1.1) + (20ms + 10ms)     for T_Filtertime > 100ms

T_positive = T_0 + (T_Filtertime + 5000ms) + (20ms + 10ms)    for T_Filtertime >= 50000ms

 

as we see above condition i want to find both negative and positive Values
