We are using you "number formatting API" (http://docs.telerik.com/kendo-ui/framework/globalization/numberformatting) to display the numbers on our webpage. For that, your API works fine as long as we round the numbers. E.g.: kendo.toString(10.12, "n0"); // will result in 10 kendo.toString(10.99, "n0"); // will result in 11 But we have some use-cases where we have to cut/truncate the number so that: kendo.toString(10.999, "n0"); // SHOULD result in 10 Here we just want to cut all decimals without any rounding, but I can´t find this option in your API documentation !! I think this is a very basic use-case which should be handled by your low level API !
