Number Bases Conversion Use Sliders to set the desired Input and Output Bases. Then Click the Flag, the Cat or Hit the Space Bar. You'll be asked to enter a number in the Input Base. If you enter a number not valid for that Number Base, you'll be asked again. Once a valid number is entered the code will convert it to its decimal equivalent before converting that to the Output Number Base.
Created by @gregatku for use in Coding Classes for Kids Unlimited, for whom I work as a Coding teacher. Uses string variables, "join <string1> <string2>", "letter i of <string>" and "length of <string>" prolifically to enable the use of non-numeric digits in both the Input and Output Numbers.
