When a decimal number has 8 digits after the decimal separator and '#' is used for formatting the precision is lost and the number is rounded.
kendo.toString(0.00000015,"###.########"
returns 0.0000002
The number should not be rounded and the precision should not be lost. The results should be the same with kendo.toString(0.00000015,"n8")
and kendo.toString(0.00000015,"0.00000000")
