But lerp is funnier, and they can just ask about it to another Scratcher or in QAS

Let's remove all the text from the blocks and replace them with numbers, and just wait for all the questions to flood in about which block is which. That would be “hilarious”.

What does “lerp” mean in this context, and how can it be used?

Lerp is just linear interpolation, it pretty much is used to get a percentage in between 2 numbers,
so lerp(5,10,50%) = 5, lerp(5,10,100%) = 10, lerp(5,10,0%) = 5

wait
cant i just use snap?

Keep in mind that scratch has tons of beginner coders in it. New Scratchers probably won’t understand what that means unless they are an expert at math.

“lerp” is short for linear interpolation.

It's basically blending between two numbers

Here's a definition (not optimized):

define (lerp from (a::custom) to (b::custom) % (percentage::custom) :: operators
return ((((1) - ((percentage::custom) / (100))) * (a::custom)) + (((percentage::custom) / (100)) * (b::custom))) :: custom

Examples:
At 0%, number a is returned
At 100%, number b is returned
At 50%, the number halfway between a and b is returned
At 25%, the number 1/4 of the way from a to b is returned

Usually instead of 0% to 100% a number between 0 and 1 is used, but this could also work.

ima try to make this in Snap!

Shouldn't this just go in the Operators category though (it was originally called Numbers but was renamed because string handling blocks were implemented in Scratch 1.4), instead of a new category?
Anyway, Scratchers, especially newer ones, might not know or understand what lerp means and/or does.

Well, this is a suggestion for adding the block into Scratch.

I can't understand the concept

Then say “number ___ % from _ to _”
