Estimated time remaining, what am I missing?

Question

I think my logic is flawed....

in a loop I have:

int seconds = (int) (elapsed.TotalSeconds / ItemPos) * (Count - ItemPos);

this loop updates approximately once per second....

the problem I have is that seconds always ends up with a zero (0) value.

this is because the ItemPos value is always higher after first loop than elapsed.TotalSeconds.

So for example:

if 3 seconds pass

ItemCount = 20 , so 3/20 = 0.15 - rounds to zero.... 0 * anything = 0......

What am I doing wrong?

Answer 1

Your expression is interpreted as

( (int)(elapsed.TotalSeconds / ItemPos) ) * (Count - ItemPos);

You have to delay the type-cast, all you need is an extra pair of ():

 //int seconds = (int)   (elapsed.TotalSeconds / ItemPos) * (Count - ItemPos)  ;
   int seconds = (int) ( (elapsed.TotalSeconds / ItemPos) * (Count - ItemPos) );
