Why does the variable become rounded?

[LLLLLLL]

I have an HTML5 audio player that gets created dynamically. Elsewhere the variable is declared:

var default_volume = 0.8;

 

Then I set the volume for the player ...

player.setAttribute( 'volume', default_volume );

 

Debugging shows default_volume is 0.8, but once set, "volume" is changed to 1

 

Why is there rounding? How can I make it maintain the value I chose?

Well that would be the player itself changing the value, wouldn't it? What player?

Player is an audio element

 

var player = document.createElement( 'audio' );

player.setAttribute( 'volume', default_volume );

And HTML 5 does say it's a value between 0.0 and 1.0.

 

What browser? And is the volume being set correctly (it's just that you can't get the right value)?

does it round down?

If you use setAttribute, you would need to use getAttribute to see the value.

e.g.

var player = document.createElement( 'audio' );
player.setAttribute('volume', 0.;
alert(player.getAttribute('volume')); // alerts 0.8
alert(player.volume); // alerts 1

// setting the volume directly
player.volume = 0.8;
alert(player.volume); // alerts 0.8

Yes , I thought about that right before going to sleep last night... just set it directly.

 

Appears to be it.
