I support.

But what if we wanted to do x^50 or something? Why use 50 blocks when you could use 1?
EDIT: Support (though I started this post topic, so…)

You wouldn't need 50 blocks. I'm currently working on a x^y custom block right now, if you're interested.

Thanks. (I have Scratch 2.0, never heard of 1.4…)

There's some log things that works…

But what if we wanted, for example 84 ^ 59? There's no block for that.

There now is.

This project.

EDIT: 84 ^ 59 = 3.40782965354148e+113. Boom.

But I wanted a block that you could link to other blocks, not a project.
EDIT: An operator block.

You can go see inside, drag the custom block script into your backpack, and boom! You now have a x ^ y block! (Note: requires a variable named Result.)

…I want it implemented so that EVERY SCRATCH USER can have one, not just the code geeks.

Actually, that's not the problem. You can do set X to 1, and repeat {set X to X*84} 59 times.

The problem is like 84^(pi) or stuff. You can't repeat something pi times.

So we use logs.

But younger scratchers might not know logs, and you can't create custom returning values right now, so this would be good.

But saying PPPPPPPPLLLLLLLLLZZZZZZZ just makes you seem immature, so it's not the greatest idea to put that in your suggestion.

It's like a demand, e.g. I WANT CAKE AND IF I DO NOT GET 49620672093657 SLICES I WILL GO ON STRIKE AND AVOID WORK!!!!!!!!!!!

Calm down, please. What you ask is already suggested before several times. And don't worry, I'm sure at some point they'll add the exponent block.

The workarounds goes like this:
//short version
x ^ y = 10 ^ (y * log x)

//long version
if y = 0
set x = 1
else
tempx = x
repeat (y - 1)
x = x * tempx

your “long version” workaround isn't really the same as te short version.

The short version works for all real numbers, the long one doesn't.

Actually, 3.14 ^ 3.14 results in 30.959 on my custom block (about seven posts above). Try it. It just doesn't work with negative numbers or fractions. And my project barely involves any heavy scripting or math at all. All you need is:
- three variables
- a repeat block
- a subtraction and a multiplication block
- a set variable block

That's it. It took me like two minutes.

Please, please, please add this as an operator just like +-*/ it's a real limitation when teaching a lot of math concepts not to have exponentiation.

I know this is technically necroposting but you raise a good point! An exponent block would certainly make things easier for teachers working with Scratch!
