Math Expressions

This section explains the syntax, and available functions and scopes for the math expressions. Math expressions are used in various places in the software:

• math parameters
• exports
• CID cell formatting

When writing a math expression there will be an auto complete functionality that can help to find parameter and function names.

Syntax

When writing a math expression, parameters from the current definition or other related definitions can be accessed and functions can be called to perform operations. Basic numerical, text and boolean operators are available.

Accessing a parameter

Parameters can be accessed by their names. Note that part item parameters are accessed using the name of the part parameter with PartItem added to the end of the name.

Accessing items in a list

Items in a list can be accessed using their zero-based position in the list surrounded by square brackets [].

For example:

Event.TestEventCollection[0]

Returns the first item in the "TestEventCollection" collection.

Operators

The following numerical operators are available:

• + addition
• - subtraction
• * multiplication
• / division

The following boolean operators are available:

• < less than
• <= less than or equal
• < greater than
• <= greater than or equal
• && and
• || or
• == equal
• != not equal

The following operators are available for date time parameters:

• + addition. If the LHS is a date time and the RHS is a numerical parameter then the return value will be a new date time with the number of seconds from the RHS added to the LHS date time
• - subtraction. If the LHS and RHS of the equation are both date time parameters then the return value will be a numerical value with the number of seconds difference between the two provided dates. If the LHS is a date time and the RHS is a numerical parameter then the return value will be a new date time with the number of seconds from the RHS subtracted from the LHS date time

String concatenation

If the return types of the LHS and RHS of the + operator do not match then operator will return a string containing the concatenation of the two values. For example 1 + "test" will return "1test".

Constant values

Constant values can be defined in an expression:

• numerical: type a number, e.g. 1.23
• string: type some text surrounded by double-quotes, e.g. "test"
• boolean: type either true or false

Keywords

The following keywords are available

• null: mainly used in a boolean comparison to check if a parameter is set, e.g. FrontSpring != null
• this: represents the current scope

Scopes

The scope is an important concept to be aware of when writing a math expression. The scope defines what entity the math expression is referencing. If you are writing a math expression in a math parameter in a setup definition, then that setup definition is the current scope. You can access any parameters on that setup directly by typing the parameter name. To change scope and access a parameter from a different entity the dot-notation is used. Again using the setup as an example, to reference a parameter from the related event you would type Event. and then a list of parameters defined in the event definition will be available in the auto update

You can join as many scope changes together, for example writing Event.Championship.Name would let you access the championship name from a setup. The auto complete normally lets you find the correct scope for anything you need, but the data model documentation provides a full overview of the software.

Unit Management

Whenever a numerical parameter with a dimension and unit defined is accessed, a unit conversion can be performed to change the returned unit. This is done using square brackets, for example mCornerFL["kg"]. A list of all available dimensions and units can be found in the units documentation.
