Base Cat is an expert at converting numbers between base 2, 8, 10 and 16 (binary, octal, decimal and hexadecimal). Just state the number, its base, and the base you want to convert to, and Base Cat will calculate it for you.
Converting between bases is actually quite simple, as you'll see if you look inside. Converting to decimal is as easy as using a prefix (e.g. 0x for hexadecimal) in a math operation such as + 0. Base Cat is based on the character CATS from the 1989 game Zero Wing by Toaplan, and uses graphics from the intro sequence of that game. https://en.wikipedia.org/wiki/All_your_base You might be interested in Base Cat's buddies - Power Cat and Root Cat: https://scratch.mit.edu/projects/636328636/ https://scratch.mit.edu/projects/636397111/
