Math.Abs() not working correctly?

[Trader.Jon]

Are there any reports on Math.Abs not working correctly in NT7rc1?

I looked in the F1 help but there is no definition of correct useage, and the strategy I am working on seems to have inconsistent behaviour (which is narrowed down to Math.Abs).

Just asking, as I simplify the strategy prior to emailing to support.

Trader.Jon, I have not heard any reports of the absolute value function not working correctly. I just tested this out and everything is working as expected. Can you post the code you're using?

This code:

protected override void OnBarUpdate()
{
    if (CurrentBar == 0)
    {
        double positive = 3.14;
        double negative = -4.13;
        
        double abs_pos = Math.Abs(positive);
        double abs_neg = Math.Abs(negative);
        
        Print("abs_pos (should be 3.14): " + abs_pos);
        Print("abs_neg (should be 4.13): " + abs_neg);
    }
}

produces this output:

abs_pos (should be 3.14): 3.14
abs_neg (should be 4.13): 4.13

Austin,

Thanks for the detailed response. I have a feeling, after seeing your post, that I am not using it correctly, but I am not getting any compile errors, or use errors in the logs either. Do I only use it with doubles?

The strategy framework has restrictions on its use, but I can email it to your attention.

I am also sending screen shot .

Jon, I've replied to your email as well, but this function should not be giving you false answers. It is a very straight forward method, and you can feed it basically any data type you want and you will get the correct absolute value.

The indicator I was using does a recalculate+repaint several bars back into past and was the cause of the annoyance ... or rather my use of that indicator was the cause of my annoyance. Thanks for the input!
