+Format specifiers can also include a presentation type, which 
+controls how the value is formatted.  For example, floating-point numbers
+can be formatted as a general number or in exponential notation:

+    '3.75'
+    >>> '{0:e}'.format(3.75)

+A variety of presentation types are available.  Consult the 2.6
+documentation for a complete list (XXX add link, once it's in the 2.6
+docs), but here's a sample::
+
+        'b' - Binary. Outputs the number in base 2.
+        'c' - Character. Converts the integer to the corresponding
+              Unicode character before printing.
+        'd' - Decimal Integer. Outputs the number in base 10.
+        'o' - Octal format. Outputs the number in base 8.
+        'x' - Hex format. Outputs the number in base 16, using lower-
+              case letters for the digits above 9.
+        'e' - Exponent notation. Prints the number in scientific
+              notation using the letter 'e' to indicate the exponent.
+        'g' - General format. This prints the number as a fixed-point
+              number, unless the number is too large, in which case
+              it switches to 'e' exponent notation.
+        'n' - Number. This is the same as 'g', except that it uses the
+              current locale setting to insert the appropriate
+              number separator characters.
+        '%' - Percentage. Multiplies the number by 100 and displays
