Changing slider values do not work properly when percent change of a step is less than one.

i'm not sure I quite understand why this code didn't work before. If the min was
0 and the max was 5, wouldn't this move by 10%, or 0.5, and give values of 0.5,
1.0, 1.5, etc.?

If these were being truncated to integers, where did that happen?

+    if (fabs(step) < 1)
+        step = percentChange > 0 ? 1 : -1;
+
+    value += step;
     setValue(String::number(value));
 
     axObjectCache()->postNotification(node(), AXObjectCacheImpl::AXValueChanged);
 }
