Overview
One function, one predictable operation
This is not an expression evaluator: name a function first, then pass its arguments. Domain and division checks are explicit, and trigonometric functions use radians; use deg2rad or rad2deg when working with degrees.

How to use it
The first argument names the function; subsequent arguments are numbers in its documented order. Angles for sin, cos, tan and inverse trigonometric functions use radians; convert with deg2rad and rad2deg. round accepts an optional precision;
Limits and safety
Inputs are validated: a negative square root, division by zero or logarithm with base 1 returns an error. Results use floating-point arithmetic; rounding and large values have finite precision. Decimal numbers use a dot (a single comma is accepted). pi, e, inf and nan are special tokens, not variables or a general expression language.

Install and manage
Install the current compatible version. Choose Base for the complete feature set or Minimum for the reduced package; use upgrade to update a module that is already installed.
Base and Minimum are two packages of the same current module release, not separate command versions.
Minimum package
Install the reduced package. Local reference is omitted;
install math -mExact public version
Install exactly this published version.
install math -v 1.1.4Check or update
Ask upgrade to check compatibility and replace the installed block only when needed.
upgrade mathRemove module
Remove the extension block while leaving the core and unrelated modules intact.
install math -uExamples
Examples are copyable command lines, not actions executed by this website. Review paths, permissions and destructive flags before running them on a real project.
