Post subject:  Need help with adding a timer
What is it you are trying to achieve?
I want my program to have a timer


What is the problem you are having?
Cant add the timer


Describe what you have tried to solve this problem
I tried using the Tuting Help, and different methods to add a timer.

The function your looking for is: Time.Elapsed

startTime = Time.Elapsed
....code...
currentTime = Time.Elapsed
timeSinceStart = currentTime - startTime

I'm guessing your trying to do a Who Wants to be a Millionaire thing. Just make sure you reset the starting time for each question and that the value for Time.Elapsed is in milliseconds.

Post subject:  RE:Need help with adding a timer
Ok, but I stated this

var startTime: real
var currentTime: real
var timeSinceStart: real

are they soppose to be real?

And It figured out its in milliseconds. I did this

startTime:= Time.Elapsed
.. THE CODE ..
currentTime:= Time.Elapsed
timeSinceStart:= (currentTime - startTime)*1000

But the output I got was weird. Something like this: 9.289e6

How come I get some letter in between?

Post subject:  RE:Need help with adding a timer
When a letter is given within a number for example 'e', you should know that you have hit the maximum integer value supported in Turing. Correct me if I am wrong. The best way to stop that is to check your math to see if all is correct. Also setting limits.

By the way I couldn't help you in class today because it would have been cheating.

You did nothing wrong but you should work on efficiency. The teacher doesn't teach efficiency all that greatly...

You should attempt on getting a clean system. I recommend though converting miliseconds to seconds.

I tried adding a *1000 and making it like this

timeSinceStart:= (currentTime - startTime) *1000

I still got the " e "

Let me examine the problem, also you should not be discussing your summative on this page because the teacher will be looking. Smile

Found the error, your math is off. You do not multiply when you do miliseconds to seconds....

Post subject:  RE:Need help with adding a timer
Turing:
timeSinceStart := (currentTime - startTime) / (1000) * (1000) div (1) / (1000)
% I didn't test that above but that should round it...

timeSinceStart := (currentTime - startTime) / 1000
% This works...

Thanks you both guys. It worked ^_^

Post subject:  RE:Need help with adding a timer
Ok, I want it to output the time in minutes. But it doesent work. I put this

timeSinceStart := (currentTime - startTime) / (1000) * (1000) div (1) / (1000)

and tried this

timeSinceStart := (currentTime - startTime) / 10000

dident work, I also timed for 1 minute, and I got like 0.6 minutes or like 0.06 minutes.

what am I doing wrong?

Post subject:  RE:Need help with adding a timer
Time.Elapsed gives you times in milliseconds.

A difference between two times measured with Time.Elapsed will be in milliseconds.

code:

seconds = (current - start) div 1000  % 1000ms = 1s
minutes = seconds div 60  % 60s = 1m
minutes = (current - start) div 60000

Your code would be so much better if you used procedures along with a bit of File I/O. Not only would you save yourself a ton of work, but you would learn actual programming skills by using these techniques.

so this would be my code?

Turing:
timeSinceStart := (currentTime - startTime) div 60000


and that will give me minutes?
