@export var x: Array[String]
```

### Minimal reproduction project

n/a
float rel = mm->get_relative().x;
		if (rel == 0) {
			return;
		}
		if (flip) {
			rel = -rel;
		}
		float val = get_edited_property_value();
		bool sg = val < 0;
		val = Math::absf(val);
		val = Math::log(val) / Math::log((float)2.0);
		
		val += rel * 0.05;
		val = Math::pow(2.0f, val);
		if (sg) {
			val = -val;
		}
		
		
		if (Math::is_zero_approx(val)) {
			val = 0.00001;
		}
		
		
		val = CLAMP(val, -1'000'000, 1'000'000);
		emit_changed(get_edited_property(), val);
		easing_draw->queue_redraw();
