-A floating point number is expressed as a decimal number in the form of
-a sequence of decimal digits followed by a decimal point, followed by decimal digits,
-followed by an exponent indicated by E or e followed by a sign
-and one or more decimal digits. The various parts can be omitted, see \lstinline!UNSIGNED_REAL! in~\cref{lexical-conventions} for
-details and also the examples below. The minimal recommended range is
-that of IEEE double precision floating point numbers, for which the
-largest representable positive number is 1.7976931348623157E+308 and the
-smallest positive number is 2.2250738585072014E-308. For example, the
-following are floating point number literal constants:
+A floating point number is expressed as a decimal number in the form of a sequence of decimal digits followed by a decimal point, followed by decimal digits, followed by an exponent indicated by \lstinline!E! or \lstinline!e! followed by a sign and one or more decimal digits.
+The various parts can be omitted, see \lstinline[language=grammar]!UNSIGNED-REAL! in~\cref{lexical-conventions} for details and also the examples below.
+The minimal recommended range is that of IEEE double precision floating point numbers, for which the largest representable positive number is $1.7976931348623157\times10^{308}$ and the smallest positive number is $2.2250738585072014\times 10^{-308}$.
+For example, the following are floating point number literal constants:
