Hi,

I have a UDT tag with float type & data is coming directly from PLC. I am getting the decimal points up to 8 digits. I want to restrict this to 3 digits max. For example: 12.093383; I want to limit it to 12.093 only. How to do this… This is a real time tag,

You control the display format of the number. See the “Number Format Pattern” property in components like the [Numeric Label](https://docs.inductiveautomation.com/display/DOC79/Numeric+Label), and the [numberFormat()](https://docs.inductiveautomation.com/display/DOC79/numberFormat) expression function. You can’t actually “fix” the number in most cases since fractional values are stored in binary and humans use decimals.
