In the monoid (,) of the natural numbers with multiplication, only and are idempotent. Indeed, = and =. In the monoid (, +) of the natural numbers with addition, only is idempotent.
i-net Clear Reports (formerly known as i-net Crystal-Clear) is a Java-based cross-platform reporting application providing a report designer and a server component to create reports in numerous output formats like PDF, HTML, PS, RTF, XLS, TXT, CSV, SVG, XML, as well as being viewable in a Java applet or Swing component.

The idempotency of plays a role in other calculations as well, such as in determining the variance of the estimator ^. An idempotent linear operator P {\displaystyle P} is a projection operator on the range space R ( P ) {\displaystyle R(P)} along its null space N ( P ) {\displaystyle N(P)} .
For example, the relation < on the rational numbers is idempotent. The strict ordering relation is transitive, and whenever two rational numbers x and z obey the relation x < z there necessarily exists another rational number y between them (for instance, their average) with x < y and y < z.
JasperReports is an open source reporting library that can be embedded into any Java application. Features include: Scriptlets may accompany the report definition, [3] which the report definition can invoke at any point to perform additional processing. The scriptlet is built using Java, and has many hooks that can be invoked before or after ...
Idempotency of entailment is a property of logical systems that states that one may derive the same consequences from many instances of a hypothesis as from just one. This property can be captured by a structural rule called contraction , and in such systems one may say that entailment is idempotent if and only if contraction is an admissible ...
BIRT has two main components: a visual report designer within the Eclipse IDE for creating BIRT Reports, and a runtime component for generating reports that can be deployed to any Java environment. The BIRT project also includes a charting engine that is both fully integrated into the report designer and can be used standalone to integrate ...
and the principle of idempotency of conjunction: P ∧ P ⇔ P {\displaystyle P\land P\Leftrightarrow P} Where " ⇔ {\displaystyle \Leftrightarrow } " is a metalogical symbol representing "can be replaced in a logical proof with".
