convert jsp load time from ms to seconds results in 0

[keydrive]

On a jsp page, I declare a startTime variable and an endTime variable. The difference is then calculated and displayed in milliseconds.

(endTime.getTime() -  startTime.getTime())

.... say that equals 208 ms

if I want the date represented in seconds I can simply divide the total by 1000.

Problem is when it's below 1000 such as the example above the value returned for display is 0 sec.

Do I need to set the decimal point somewhere?

The problem is that when you do integral division, like long/long:

long interval = ...
double seconds = interval/1000;

The division is integral division -- the result is a long and any remainder is dicarded. The solution is to do floating point division, like double/double:

double interval = ...
double seconds = interval/1000.0;

Hi BigDaddyLH,

That did the trick.

Thanks for the explanation.
