Bit shifting in skript

[uiytt]

Is your feature request related to a problem? Please describe.
So its the second time since I start using skript-mirror (I started not long ago) that I need to use bit shifting for an algorithme (>> in java)
Ex : 4>>2 = 1

Complete explanation here : https://stackoverflow.com/questions/141525/what-are-bitwise-shift-bit-shift-operators-and-how-do-they-work

Describe the solution you'd like
an expression like %object%>>%number% that return the value of the object after the shifting...

Describe alternatives you've considered
Some peoples says that:
A>>3 is equal to divise something by 8 (2 * 2 * 2)
A<<5 is equal to multiple something by 32 (2 * 2 * 2 * 2 * 2)
But this is not the exact same things, bit shifting when shifting too far remove bit, see more here

Do you have a use case for this? More often than not, bit shifts are used to manipulate bitmasks, which skript-mirror's bits expression already lets you do and in a much more readable way.

Well I wanted to do something like that :

BufferedImage img = ....

public boolean isTransparent( int x, int y ) {
  int pixel = img.getRGB(x,y);
  if( (pixel>>24) == 0x00 ) {
      return true;
  }
}

Do you know how I can make something like that with the bit expression (I don't really understand the expression well.... :/)

Please take a look at the docs for the bits expression.

Already seen it but I'm lost 🤔
Normal bit shifting only need two argument, why is there 3 to 4 args ? (Yeah I'm not really good :( )
Is this something like this :
add 3 to {_number}'s bits ?
but what are the last two arguments for ?

[btk5h]

The bits expression is not a bit shift. The entire purpose of the expression is to prevent the user from even having to think about bit shifting.

Example:
If you have a number in binary such as 0b0001001000 and you want to manipulate the bolded numbers, the bits expression will allow you to manipulate the value 0b10010 without thinking about its position in the original number.

%numbers%'[s] (bit %number%|1¦bit(s| range) [from] %number%( to |[ ]-[ ])%number%)
{_nombre}'s bit range from 1 to 1 -> give the first bit ?
