   XEmacs supports two numeric data types: @dfn{integers} and
 @dfn{floating point numbers}.  Integers are whole numbers such as
-@minus{}3, 0, 7, 13, and 511.  Their values are exact.  Floating point
+@minus{}3, 0, #b0111, #xFEED, #o744.  Their values are exact.  The
+number prefixes `#b', `#o', and `#x' are supported to represent numbers
+in binary, octal, and hexadecimal notation (or radix).  Floating point
 numbers are numbers with fractional parts, such as @minus{}4.5, 0.0, or
-2.71828.  They can also be expressed in exponential notation:
-1.5e2 equals 150; in this example, @samp{e2} stands for ten to the
-second power, and is multiplied by 1.5.  Floating point values are not
-exact; they have a fixed, limited amount of precision.
