# New on CTAN: numerica

The numerica 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. Other commands iterate and find fixed points of functions of a single variable, find the zeros or extrema of such functions, calculate the terms of recurrence relations, and create multi-column tables of function values.

The package’s Catalogue entry can be viewed at https://ctan.org/pkg/numerica The package’s files themselves can be inspected at http://mirror.ctan.org/macros/latex/contrib/numerica/

## 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.

Other commands iterate and find fixed points of functions of a single variable, find the zeros or extrema of such functions, calculate the terms of recurrence relations, and create multi-column tables of function values (which requires the booktabs package).
