# 🔹 ApplyTolerance

The **ApplyTolerance** node allows you to control how similar prediction values should be before they are considered identical during packet processing.

When CMC PLUS combines prediction data into network packets, the system compares the previous value with the new value.

If the difference between these values is within the defined **Precision Threshold**, they can be treated as the same value, helping reduce unnecessary data changes and improve packet optimization.

The default tolerance settings are managed automatically, but this node allows developers to define custom precision rules when needed.

#### <mark style="color:$primary;">Precision Threshold Examples</mark>

**Precision Threshold = 0**\
The value must be exactly identical. No difference is accepted.

**Precision Threshold = 1**\
The value is considered identical if it is within a difference of 1 unit.
