JM°-Classic / Atomic types / Bool - True or false


Bool - True or false

For truth values the type "Bool" exists in JM°.

Create

Ein Bool-Objekt kann wie folgt erzeugt werden:

true
TRUE

or with:

false
FALSE

Condition

Often two objects are available, which are used depending on "true" or "false". For this, e.g. Java or PHP offer the ternary operator "x ? y : z".

In JM°, the ".use" function is used for this case:

true.use( "a", "b" ).print

Das erste Argument ("a") wird bei "true", das Zweite ("b") bei "false" zurück gegeben.
