Windows 7: Minesweeper Gaming Statistics

11 Nov 2009   #1

Windows 7 Professional 64bit
Minesweeper Gaming Statistics

I don't know if this has been posted before, but I was wondering if anyone else has noticed this.

The percentage statistics are a little off for games won. I posted a picture below. It says I won 9 out of 10 games but the percentage won is 89% instead of 90%. Is there a reason for this, or is it a minor bug?

lol no offense but is this really something to worry about?

8/9 = .88888 = ~.89 = 89% (no I can't make the infinite 8 repeating symbol on here haha) so it probably just didn't calculate the last game as of that report.

Is there a way to close the game, reopen it and then see statistics before starting a new game?

It's a common programming error when using floating point which is ALWAYS +/- 0.000000000000001

You HAVE to properly round and truncate floating point math to get the correct figure.

The code "double d = 9.0 / 10.0;"

Will produce the result 0.90000000000000002 according to a test I just did. Depending on how they were actually calculating the value it could come out to be something like 0.89999999999999998. Which truncated without rounding would be 0.89. 0.89999999999999998+0.005(two place rounding value) would be 0.90500000000000003 which when truncated to two decimal places would then be 0.90 the correct answer.

Another amusing floating point bug you'll see a lot is a number being reported as "-0.0"
