Total song time error

[Lowlander]

MM has an error in the total song time it displays in the bottom of the program.

It has the same problem as I was experiencing here:

It has to do with rounding. Please let me know which version is correct the tracklisting or statusbar time.

What exactly is the error?

Just to explain how it works - MM doesn't do any rounding, all lengths are truncated to the nearest lower second. For example if you have two tracks of the same length 3:07.789, they are shown as 3:07 in the tracklist, but their total length in the statusbar is 6:15 (not 6:14).

That is the problem, MM uses no truncating for the statusbar time and does so for the tracklisting time. This leads to a total time that is higher than the sum of the tracklisting times.

Hi,

In fact, I don't think it is a bug:

When displaying a single song, it is not accurate to display numbers after the seconds..

And for a whole list, those numbers can add up quickly to some seconds, and those seconds will be used on a CD or when playing the whole list.

And it is easier to get the sum of the time in the database and do a final rounding than rouding every track and then add them up... And first option is way faster...

I just think the numbers should be consistent. Either rounding in both or no rounding at all.

Anyway it doesn't bother me, it is just that while coding for MM I found out that these numbers don't add up.

I think it is correct as is. In fact the times are always rounded down to the nearest integer. Let's take my example above, 6:14 could be shown as the total time, but it would be 1.578 secs off the correct total length (which is 6:15.578). The original values of times (including milliseconds)are sumed, not the rounded ones.
