Expression

Class: NodeDoubleExpression

Node Icon

Create a custom expression using the input values. The user can specify an arbitrary number of input values and bits, which are assigned a variable name, starting with \(a\). At least one value is mandatory. The variable names can then be used to create an expression to be calculated. As an example, to create a node that takes an input value \(a\), ads it to a second input value \(b\), and multiplies the result with \(e\) raised to the power of an input number \(c\), you would write:

(a+b)*e^c
