[Extension] Math Formulas [V3]

Thank you @Robert!

Will try to add. :+1:

Are you talking about this?


Yeah! That’s why I started with it. I had no prior knowledge of creating extensions.

Sir, I know about every single extension of yours.

You are great! :+1: You are my inspiration!

Yes I know, you can make anything simple. I’m just using Java's Math class for my experience.


Yes, I was talking about this? So the method (power) is already implemented. However, it would be nice to add another* n th root block.

*2nd root already exists

Small Update

Added Nth Root


Usage Example

P.S: Thank you @Robert for the idea!

You’re welcome :blush:.
Any other idea?
I would like to hear.

Well, you have done such a great job! This extension has a lot of blocks already. Currently I do not have other ideas.


mathematical functions are interesting of course.
how about the next one:

  • to make the functions work with the hexadecimal transformation ? for example, working with bytes … 04 6C 01 08 … as a result it is 01086C04
    or 17 329 156. (the difficulty in assembling it is to control the number greater than 10 or not) .
  • base for translation (basis) of representation of number from hexadecimal system in decimal at observance of base of numerical values (16-bit, 32,64)?
  • Translation of numeric values into alphabetic values in both directions . For example, code 31=number 1, https://upload.wikimedia.org/wikipedia/commons/thumb/4/4f/ASCII_Code_Chart.svg/369px-ASCII_Code_Chart.svg.png

Well, thank you for your interest @11119!

You can clearly see from the name of extension that it is related to mathematical formulas (formulae).

Why do you think that your proposal is related to this extension?

Maybe I’m wrong. :thinking:

I would like to do a scientific account, but can it be done?

sin or cos or tan 30

The result


Why you don’t use built-in math blocks?

I mean fractional view

Nice work, Keep it up.
As per my observation;
area of regular polygon, area of regular prism and Quadratic are not working properly. Please mark it as a suggestion. Correct me if I am wrong.

Rest all formulas working great:slight_smile:

Thank you @Asim!

Would you mind showing any example where result isn’t as expected?

wait a bit. I will show.

area of regular polygon is not even giving result.(rest all gives result)
Quadratic formula gives not a number ( please add how to use it)
volume of prism is simple base*height while you can see its formula from the picture.
volume of sphere also gives wrong answer (picture is attached).

Area of Regular Polygon is working fine. Maybe issue in your blocks.
Result on web:


Volume of prism is working fine.

Yes, it seems that something wrong here. I’ll try to fix it as soon as possible.

I’ll see what’s wrong here too.

Thank you for pointing out @Asim!
I’ll try to fix ASAP!
