5.1 Functions

This section gives a complete reference of all functions, commands and special variables of the SINGULAR kernel (i.e., all built-in commands). See standard_lib, for those functions from the standard.lib (this library is automatically loaded at start-up time) which extend the functionality of the kernel and are written in the SINGULAR programming language.

The general syntax of a function is

[target =] function_name (<arguments>);

If no target is specified, the result is printed. In some cases (e.g., export, keepring, setring, type) the brackets are optional. For the commands kill, help, break, quit, exit and LIB no brackets are allowed.
