# torch.set_flush_denormal

torch.set_flush_denormal(mode) → bool

  Disables denormal floating numbers on CPU.

  Returns `True` if your system supports flushing denormal numbers and it successfully configures flush denormal mode. `set_flush_denormal()` is only supported on x86 architectures supporting SSE3.

  Parameters:

    mode (bool) – Controls whether to enable flush denormal mode or not

  Example:

      >>> torch.set_flush_denormal(True)
      True
      >>> torch.tensor([1e-323], dtype=torch.float64)
      tensor([ 0.], dtype=torch.float64)
      >>> torch.set_flush_denormal(False)
      True
      >>> torch.tensor([1e-323], dtype=torch.float64)
      tensor(9.88131e-324 *
             [ 1.0000], dtype=torch.float64)
