Help Me With Volume Control!

[ShotgunSnipist]

So right now I have it changing volume control with:
MediaPlayer.Volume -= .03f;
And It's 'Printing' It with:
String Volume = "Volume: " + MediaPlayer.Volume.ToString();


Nothing is Wrong With the code, but when you adjust the volume it goes into odd decimals. Pressing down then up will give me .9999 instead of 1.

My question is, how could I code this to Not only stop going into decimals but make it 1-20 (in increments of 1) instead of 0 to 1 (in increments of .03).

Thanks.


Another little problem I have,
I have
DateTime.Now.ToString()
Being 'printed' and it is a few hours off. How could I adjust this? (in game, pressing left and right)

Welcome to floating point inaccuracy. On any computer that works in binary you will always see this when doing floating point arithmetic. The only way to solve it is use integers . Something like:

int myVolume = 100;
MediaPlayer.Volume = myVolume / 100f;
string volume = "Volume: " + myVolume + "%";

Then you'll always see an even number displayed as a percentage of the volume. But basically when it comes to floating point math on a computer, you are never guaranteed for it to be exact. That's just how it is.

And for the record .9 repeating == 1

Worked awesome!

If you did mean to put == (2 of them) there,
Yes I suppose that would work...
But that's a hell of a lot of code because it did it for every increment.

No, mathematically speaking, .9 repeating is exactly the same value as 1

1/3 = .3 repeating

.3 repeating * 3 = 1

.3 repeating * 3 also = .9 repeating

Oh okay. I thought you meant to program into the program to recognize .9999 and make it display 1.

If so I'm SOO interested. I have programming experience. Your help would be apprieciated
