C= app.CollectionEditField.Value;
S= app.ServingEditField.Value;
app.cycle=0;
cycle_t=app.cycle;
app.FC=0;
F_C=app.FC;
app.F=0;
F_1 =app.F;
SC= S;
while F_C<=double(SC-0.000001))
F_1= double(S*C);
S= double(S-F_1);
F_C= double(F_C+F_1);
Fo= F_C;
cycle_o= (cycle_t+1);
end
app.CycleEditField.Value= cycle_o;
app.FInalCollectionEditField.Value= Fo;

F_C=0;
cycle_t=0;
S=15;
C=0.02;
SC=S;
while F_C <=SC-0.000001
F_1= S*C;
S= S-F_1;
F_C= F_C+F_1;
Fo= F_C;
cycle_o=cycle_t+1;
end
>> cycle_o
cycle_o =
1
>> F_C
F_C =
15.0000
>> SC
SC =
15

I have no klew what you're trying to do here, but your first line in the while construct sets F_1 to the S*C product and then the control variable F_C is set to F_C+F_1 which is F_1 since F_C is initialized to zero. Thus, the inequality
F_C <= SC-eps
fails and the loop terminates.

Try this in command window. You will see cycle number is showing 860.
FC=0;
C=0.02;
cycle=0;
>> S=35;
>> SC=S;
F=0;
while FC <=SC-0.000001
F= S*C;
S= S-F;
FC= FC+F;
cycle=cycle+1;
end

From my understanding you are not able to run while loop in your code. I dont see anything wrong with the loop or with the code that you mentioned in the comment, I would advice you to check if the varaibles
C= app.CollectionEditField.Value;
S= app.ServingEditField.Value;
are as expected.

As I am trying to design the app so, my intension is to apply C and S value using app numerical box. When I will give this value in the box then they will do the calculation using the while loop. And after finishing the the calculation it will show the result in another box. Can you kindly say me, what exactly I have to do for design such app? I am getting the result from the command window but when I am using in app its not working?
