Wissenschaftlicher Taschenrechner

    Mit diesem Script kann man einen schönen, funktionalen Taschenrechner "basteln". Die Variablen erklären sich von selbst. So kann man z. B. die Farben nach den jeweiligen Bedürfnissen anpassen. Einfach mal ein wenig probieren.


    Und los geht's:

    Hi AlleMann,
    eigentlich wollte ich mit dem Rechner nur den Tangens eines rechten Winkels ausrechnen(bzw. sehen, ob eine und welche Fehlermeldung kommt)..
    Als da nur Blödsinn rauskam, dachte ich als Erstes:
    "Mist, Bedienungsfehler.."(reiner Selbstschutz, javascript ist nicht meine Stärke), aber da half ja nix außer Editor aufrufen und im Source-Code rumwühlen(über den Störfaktur Werbung reden wir mal nicht).
    Und richtig, da war es dann auch schon:
    In der Konstanten-Anweisung für PI steht 3,14.. und das ist verkehrt(witzig übrigens, daß die anderen Konstanten richtig sind..)!
    Ich habe es auf 3.14.. berichtigt und seitdem funktioniert das Grundgerüst eines Taschenrechners ;-)
    Wie sage ich immer so richtig:
    Programmieren bedeutet nicht, zu wissen, wie die Kopierfunktion des Editors bedient wird, manchmal läßt sich ein wenig Sachkenntnis nicht vermeiden..
    Ich hoffe, das reicht als Einstand ;-)
    Viele Grüße aus 1200jährigen Landeshauptstadt Magdeburg
