All Implemented Interfaces:

TemplateModel, TemplateNumberModel, java.io.Serializable

public final class FastNumber
extends java.lang.Object
implements TemplateNumberModel, java.io.Serializable

An unsynchronized, immutable implementation of the TemplateNumberModel interface. This avoids the need for synchronization, since we don't have any situations where the underlying value changes.

1.8
