# Properties (Expression Converter)

[Decimal Places]
Used when [Dec], [FloatFixed], [FloatAuto], or [FloatScientific] is selected in [Format]. Set the number of decimal places for the converted value. Setting Value Range: 0 - 19
Note: When, in the [Current Value], a source property is assigned and either [Unit], [Scale], or [Expression] converter is used, [Decimal Places] of Converter property takes priority over [Decimal Places] of object property. When using one of the float formats [FloatFixed], [FloatAuto], or [FloatScientific] in a numeric display, select either a [REAL] or [LREAL] variable. If you use other data types, a floating point number may not be represented correctly.

[Rounding]
Select how to handle fractional values with decimal places that exceed the number of digits set in [Decimal Places].
