Template:Pow/doc

This is a documentation subpage for Template:Pow.
It contains usage information, categories, and other content that is not part of the original template page.

Usage

This template provides an expression for a power. It checks whether base and exponent both have an integer value. If so, they are converted to type integer and Template:Powint is applied, otherwise the power is applied directly.

Thus the highest accuracy is achieved, and the result is of type integer where possible, for display and accurate subsequent computations.

Syntax
