Version 3.0.0 of numerica requires a LaTeX distribution from October 2020 or later (when xparse became available in LaTeX2e systems), as well as the packages amsmath and mathtools. V.3.0.0 allows use of the decimal comma, evaluates multiple expressions within the one \eval command, and can output results in the form of fractions. See the documentation, numerica.pdf, on these (and many other) enhancements, and for how to use the package.

## numerica – Numerically evaluate mathematical expressions in LaTeX form

This package defines a command to wrap around a mathematical expression in its LaTeX form and, once values are assigned to variables, numerically evaluate it. The intent is to avoid the need to modify the LaTeX form of the expression being evaluated. For programs with a preview facility like LyX, or compile-as-you-go systems, interactive back-of-envelope calculations and numerical exploration are possible within the document being worked on.

The package requires the bundles l3kernel and l3packages, and the amsmath and mathtools packages.
