torch.trunc
torch.trunc(input, *, out=None) -> Tensor
Returns a new tensor with the truncated integer values of the
   elements of "input".
For integer inputs, follows the array-api convention of returning a
   copy of the input tensor.
Parameters:
      input (Tensor) -- the input tensor.
Keyword Arguments:
      out (Tensor, optional) -- the output tensor.
Example:
  >>> a = torch.randn(4)
  >>> a
  tensor([ 3.4742,  0.5466, -0.8008, -0.9079])
  >>> torch.trunc(a)
  tensor([ 3.,  0., -0., -0.])
