<h1 id="function-simplifyconstant">Function simplifyConstant <a href="#function-simplifyconstant" title="Permalink">#</a></h1>
|
|
|
|
simplifyConstant() takes a mathjs expression (either a Node representing
|
|
a parse tree or a string which it parses to produce a node), and replaces
|
|
any subexpression of it consisting entirely of constants with the computed
|
|
value of that subexpression.
