 === Literal Expressions
 
-The types of literal expressions supported are strings, numeric values (int, real, hex),
-boolean, and null. Strings are delimited by single quotation marks. To put a single quotation mark itself
-in a string, use two single quotation mark characters.
+SpEL supports the following types of literal expressions.
 
-The following listing shows simple usage of literals. Typically, they are not used
-in isolation like this but, rather, as part of a more complex expression -- for example,
-using a literal on one side of a logical comparison operator.
+- strings
+- numeric values: integer (`int` or `long`), hexadecimal (`int` or `long`), real (`float`
+  or `double`)
+- boolean values: `true` or `false`
+- null
+
+Strings can delimited by single quotation marks (`'`) or double quotation marks (`"`). To
+include a single quotation mark within a string literal enclosed in single quotation
+marks, use two adjacent single quotation mark characters. Similarly, to include a double
+quotation mark within a string literal enclosed in double quotation marks, use two
+adjacent double quotation mark characters.
+
+Numbers support the use of the negative sign, exponential notation, and decimal points.
+By default, real numbers are parsed by using `Double.parseDouble()`.

+method.
