# wrong rotation transform on rig

Why when im rotating the X axis in positive values the feet "goes up"(in this example is the feet but is all the armature as well) as you can see the values in X rotation are 2.600(positive) BUT i have another armature where the foot "goes down" with the same axis with the same positive values

why this happen. as you may guess this inversion happens with negative values(for example -2.600) as well and affect the Z axis too i want my armature rotate like in the second picture, all the bones that ive been testing they behave like in the second picture, only my armature behave like this, like is the weirdo of the class

Important! Note that a roll of 180 is not the same as -180. For centered bones make sure the X and Y positions of the head and tail are 0, not -0. I had a blender version (2.91?) that used -0 and the (calculated) roll then was -180 but for 0 it was 180. The result is a mess when several bones have different signed values (+/-).
