Hello, I am new to the ignition program and I have been trying to create some new faceplates. I noticed that the slider object only produces integer values. Since the objective of the slider is to write float values in the range of -2.00 to 2.00 to an OPC tag, a script is written when the mouse click is released. The slider has been scaled up by 100 (range is now -200 and 200). The original idea was to use toFloat( slider value ) to cast the integer to a float and after that I can do basic mathematical operations to the value. However, Ignition seem to think “toFloat( )” is not a predefined function, how do I resolve this problem? Thanks in advance! ![](https://us1.discourse-cdn.com/inductiveautomation/original/2X/b/b10ad1879b84ea71f49f0f50fa4b9b7dd36f29a0.jpg) ![](https://us1.discourse-cdn.com/inductiveautomation/original/2X/d/dddc092635d6d469fdcaa51eaf1f6f2948a640bb.jpg) ---

Try ```auto value = float(event.source.value) ``` ---
