switch

This block is part of the number group and was last modified in core v12.0.4.

switch number v12.0.4

Returns a number based of the given expression.

In pins 2

expression required
value
The expression to evaluate.
default
number
The default statement to be executed.

Out pins 2

output
number
Returns the number matching the expression.
match
condition
Returns true in case a match was found.

Outputs the number pin of the case matching the value/expression pin, with matched=true; when no case matches it outputs the default pin with matched=false. Case selection is pre-computed by the engine before this block runs, values pass through without coercion, and with no selection at all the output is number=nil, matched=false.

A typical wiring for switch: the number out pin feeds cast to value.
