[[canvas-function-reference]]
|
|
== Canvas function reference
|
|
|
|
Behind the scenes, Canvas is driven by a powerful expression language,
|
|
with dozens of functions and other capabilities, including table transforms,
|
|
type casting, and sub-expressions.
|
|
|
|
The Canvas expression language also supports <<canvas-tinymath-functions>>, which
|
|
perform complex math calculations.
|
|
|
|
A *** denotes a required argument.
|
|
|
|
A † denotes an argument can be passed multiple times.
