Arithmetic, Logical and Comparison Operators

Here is a list of the available operators in a SIL SIL™ program and detailed usage information.

...

For each operator and LHS type, we define two lists: valid types and convertible types. The list of convertible types is based on Type Conversionconversion. This creates three cases:

...

Explanations and Usage

?:boolean, <type>, <type><type>
Code Block
<condition> ? <ifTrueValue> : <ifFalseValue>

If <condition> is true, returns <ifTrueValue>, otherwise returns <ifFalseValue>.

Note that <ifTrueValue> and <ifFalseValue> must have same type.

The Indexing Operator

...

The indexing operator can also be used with certain simple types (not arrays) and a specific value to provide additional functionality.
