Using the Mathematics Development Engine Extension
The Mathematics Development Engine Extension provides three blocks for use in the behavior and events editor.
Basic Evaluation Block
Input: Text Output: Float
The basic evaluation block takes as input an infix mathematical expression (e.g. "9+6"), and returns the result as a number type.
The block is completely numerical. Several functions, such as the trigonometric functions, are supported. A complete list of supported functions is provided in this chapter.
Symbolic Evaluation Block
Input: Text, Text Output: Float
The symbolic evaluation block takes two inputs, and returns the result as a number type.
Input 1: An infix mathematical expression (e.g. "6*x+4")
Input 2: A substitution. Input should be of the form [variable]=[value]. Multiple substitutions can be separated with commas.
The block is completely numerical. For proper evaluation, a value must be substituted for every variable.
Symbolic Comparison Block
Input: Text, Text, Text Output: Boolean
The symbolic evaluation block takes three inputs, and returns the result as a boolean type.
Input 1: An infix mathematical expression (e.g. "6*x+4")
Input 2: A second infix mathematical expression
Input 3: A substitution. Input should be of the form [variable]=[value]. Multiple substitutions can be separated with commas.
The block makes the specified substitutions, and returns TRUE if Input 1 equals Input 2. Otherwise, FALSE is returned.
