Further Examples

This breaks digits into blocks of length 3.

In[1]:=  

Out[1]//NumberForm=

You can specify any string to use as a separator between blocks of digits.

In[2]:=  

Out[2]//NumberForm=

This gives an explicit plus sign for positive numbers, and uses | in place of a decimal point.

In[3]:=  

Out[3]//NumberForm=
