Ext.util.Format.number add extra decimals

I'm using method "Ext.util.Format.number" to convert a value to string, according to a specific format. But this method add extra (parasite) decimal.

With this code :

var strValue = Ext.util.Format.number(value, this.displayFormat);

For example if

After conversion, strValue is not equals to 102.15 but to 102.15000000000001

Is there any way to be sure that "Ext.util.Format.number" never add extra/parasite decimal ?

Thanks

Since 102.15 and 102.15000000000001 are not distinguishable(*) in JavaScript, it's up to you to choose a number format that does not include that many digits. Ext.util.Format.number has no way to determine the correct output.

(*) try 102.15 === 102.15000000000001 in your javascript console - it returns true

Do parseFloat(strValue) after that formatting. I think thats what you are looking for.
