calculating with add - where is the error?

gkaefer

where is the error in the add statement, I mean the trace gives me not %1(=0.31) + 0.1 = 0.41 in result for volume-plus, but it shows:

Code

INFO: PARAMETER 1 is 0.31
INFO: VOLUME-ACTUAL is 0.31
INFO: VOLUME-PLUS is add(0.31, 0.1)

heres my action:

Code

<action name="soundsettings">
		set(plugin[vars].volume-actual,%1);
		trace('PARAMETER 1 is ', %1); 
		trace('VOLUME-ACTUAL is ', get(plugin[vars].volume-actual)); 
		if(	%1 LT 1.0, set(plugin[vars].volume-plus,add(%1, 0.1)));
		trace('VOLUME-PLUS is ', get(plugin[vars].volume-plus));
	</action>

thanks in advance!

Hi,

instead of:

Code

set(plugin[vars].volume-plus,add(%1, 0.1));

use:

Code

add(plugin[vars].volume-plus, %1, 0.1);

see also:
https://krpano.com/docu/actions/#add

an action can't be used as parameter for an other action, and there are no return values,

best regards,
Klaus

why is the result in my add calculation 0.30000000000000004 and not 0.3 ?

$1 is 0.2 than I do add 0.1 for VOLUME-PLUS and do sub 0.1 for VOLUME-MINUS

debug output:

Code

INFO: PARAMETER 1 is 0.2
INFO: VOLUME-ACTUAL is 0.2
INFO: VOLUME-PLUS is 0.30000000000000004
INFO: VOLUME-MINUS is 0.1

my action:

Code

<action name="soundsettings">
		set(plugin[vars].volume-actual,%1);
		trace('PARAMETER 1 is ', %1); 
		trace('VOLUME-ACTUAL is ', get(plugin[vars].volume-actual)); 
		if(	%1 LT 1.0, add(plugin[vars].volume-plus,%1,0.1),set(plugin[vars].volume-plus,1.0));
		if(	%1 GT 0.0, sub(plugin[vars].volume-minus,%1,0.1),set(plugin[vars].volume-minus,0.0));
		showlog();
		trace('VOLUME-PLUS is ', get(plugin[vars].volume-plus));
		trace('VOLUME-MINUS is ', get(plugin[vars].volume-minus));
	</action>

Liebe Gruesse,

PS: if I use not 0.2 but 2 and do add 1 and sub 1 instead of the 0.1 than the calculations are correct....

done all on Win7 64 bit with IE 9 and

I think it has to do with some float values.

Try to round them

roundval(get(plugin[vars].volume-minus), 2);

calculating with add - where is the error?
