# Properties (Scale 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.

[Retain range]
Changes the process when the source or output value exceeds the set range. If the check box is selected, the [Minimum (Output)] or [Maximum (Output)] is used as the output value when the source value exceeds the [Minimum (Source)] or [Maximum (Source)] value. If the check box is cleared, the [Maximum (Source)], [Maximum (Output)], [Minimum (Source)], and [Minimum (Output)] are as a ratio to calculate the relative output value.

[Maximum (Source)] / [Maximum (Output)] / [Minimum (Source)] / [Minimum (Output)]
Select the conversion input range ([Minimum (Source)] / [Maximum (Source)]) and conversion output range ([Minimum (Output)] / [Maximum (Output)]). The output value is calculated based on the source/output range. Setting Value Range: -2147483648 - 2147483647

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