   Although `NaN` by definition isn't equal to itself, so this implementation
   also considers all `NaN`s different from each other by default:
 
-     iex> Nx.all_close(Nx.tensor(:nan), Nx.tensor(:nan))
-     #Nx.Tensor<
-       u8
-       0
-     >
+      iex> Nx.all_close(Nx.tensor(:nan), Nx.tensor(:nan))
+      #Nx.Tensor<
+        u8
+        0
+      >
 
-     iex> Nx.all_close(Nx.tensor(:nan), Nx.tensor(0))
-     #Nx.Tensor<
-       u8
-       0
-     >
+      iex> Nx.all_close(Nx.tensor(:nan), Nx.tensor(0))
+      #Nx.Tensor<
+        u8
+        0
+      >
 
   We can change this behavior with the `:equal_nan` option:
 
-     iex> t = Nx.tensor([:nan, 1])
-     iex> Nx.all_close(t, t, equal_nan: true) # nan == nan -> true
-     #Nx.Tensor<
-       u8
-       1
-     >
-     iex> Nx.all_close(t, t, equal_nan: false) # nan == nan -> false, default behavior
-     #Nx.Tensor<
-       u8
-       0
-     >
+      iex> t = Nx.tensor([:nan, 1])
+      iex> Nx.all_close(t, t, equal_nan: true) # nan == nan -> true
+      #Nx.Tensor<
+        u8
+        1
+      >
+      iex> Nx.all_close(t, t, equal_nan: false) # nan == nan -> false, default behavior
+      #Nx.Tensor<
+        u8
+        0
+      >
 
   Infinities behave as expected, being "close" to themselves but not
   to other numbers:
 
-     iex> Nx.all_close(Nx.tensor(:infinity), Nx.tensor(:infinity))
-     #Nx.Tensor<
-       u8
-       1
-     >

-     iex> Nx.all_close(Nx.tensor(:infinity), Nx.tensor(:neg_infinity))
-     #Nx.Tensor<
-       u8
-       0
-     >

-     iex> Nx.all_close(Nx.tensor(1.0e30), Nx.tensor(:infinity))
-     #Nx.Tensor<
