|
Out[4]=
|
Here is a nested list.
In[5]:=
|
This gives the sum of the elements of  .
In[6]:=
|
Out[6]=
|
Total also gives the sum of symbolic lists.
In[7]:=
|

|
Here is a list of two matrices.
In[14]:=
|
Out[14]=
|
This adds the matrices.
In[15]:=
|
Out[15]//MatrixForm=
|
This adds the rows of the sum of the matrices.

|
Out[16]//MatrixForm=
|
This adds all the elements of the matrices.
In[17]:=
|
Out[17]=
|
This gives the precision of a machine number on any given computer, whether 16-bit, 32-bit, or 64-bit.
In[18]:=
|
Out[18]=
|
Here is a list of numbers.
In[19]:=
|
Out[19]=
|
Neither Plus nor Total register the sum of the small numbers in  .
In[20]:=
|
Out[20]//FullForm=
|
In[21]:=
|
Out[21]//FullForm=
|
Using the option  Total gives a result closer to the true sum.
In[22]:=
|
Out[22]//FullForm=
|
In[23]:=
|
Out[23]//FullForm=
|
