+Subject: [PATCH] Fix FTBFS.
+
+Previous boost library (1.75) may implicitly include cmath, but the
+latest version (1.76) does not, so the calls to exp are undefined. This
+commit include cmath in script_translator.cc and table_translator.cc to
+fix the issue (#462).

+Subject: [PATCH] fix: qualify std::exp after including <cmath>
+
+As noted in #462, including <cmath> only guarantees that std::exp is
+declared, so calling exp(double) unqualified is not portable.

+Squashed commit with a style change to the original PR:
