I was wondering what would be the mathematical solution to tile properly an image to fit the composition while taking the scale as a parameter.

thanks

You didn't mention anything about scaling. It helps to be precise! Simply multiply the expansion values by the inverse of the scaling factor, in this case 2. Example:

mDown=(cHei-mY+mHei+0.5)*2;

I did precise it in the question and the calculation is highly inacurate or the software has some issues even after trying multiple alteration of the formula even before asking the question.

When the scale is negative the image is too small & way too big when it is over 100% wich create major memory issues.

please try it out on your side before please!

Repetile uses absolute pixel values, so it's as simple as figuring out the difference between comp size and layer size, possibly also accounting for position if it's not centered. Example:

mWid=thisLayer.width;
mHei=thisLayer.height;
cWid=thisComp.width;
cHei=thisComp.height;
mX=thisLayer.transform.position[0];
mY=thisLayer.transform.position[1];

mDown=cHei-mY+mHei+0.5;
mUp=mY-mHei*0.5;
mRight=cWid-mX+mWid*0.5;
mLeft=mX-mWid*0.5;

Insert the respective code bits in the corresponding controls of the effect.
