 \subsection{Constants}\label{subsec:retrieving-constants}
 
-For some functions constants are used.
+For some functions, constants are used.
 These constants are typically implemented as C macros (\texttt{\#define}) in the source code.
 This makes the source code more readable (and portable).
-Constants are represented as an integer again followed by a colon, this time without any special characters to distinguish them from other types.
