 Without question, the smallest building blocks in Modelica are single characters belonging to a character set.
 Characters are combined to form lexical units, also called tokens.
 These tokens are detected by the lexical analysis part of the Modelica translator.
-Examples of tokens are literal constants, identifiers, and operators.
+Examples of tokens are literals, identifiers, and operators.
 Comments are not really lexical units since they are eventually discarded.
 On the other hand, comments are detected by the lexical analyzer before being thrown away.

 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 $2.2250738585072014\times 10^{-308}$.
