   @xidulu Thanks a lot for your user experience comment. In this case, using `np.finfo('float32').eps` returns the machine epsilon which is far from denormal number. Therefore, these 2 flags shouldn't affect your clipping. To create denormal number from machine epsilon you have to take it to ~6th power.
   ```Python
   import daz
   daz.set_ftz()
   daz.set_daz()
   
   np.power(np.finfo('float32').eps, 5, dtype=np.float32)
   >>> 2.4074124e-35
   
   np.power(np.finfo('float32').eps, 6, dtype=np.float32)
   >>> 0.0
   ```
