The semicolon is a undocumented extension (I noticed it in the

One of these days I have to write the pending section in th elow level
manual and also explain this:
\starttext
\ifnum 10 = 11 wrong \else okay \fi
\ifnum 10 != 11 okay \else wrong \fi
\ifnum 10 !> 11 okay \else wrong \fi
\ifnum 10 !< 11 wrong \else okay \fi
\ifnum 10 ≤ 11 okay \else wrong \fi
\ifnum 10 ≥ 11 wrong \else okay \fi
\ifnum 10 ≰ 11 okay \else wrong \fi
\ifnum 10 ≱ 11 wrong \else okay \fi
\ifnum "F0 ∈ "F0 okay \else wrong \fi
\ifnum "F0 ∉ "F0 wrong \else okay \fi
\stoptext
These new features are mentioned in the Luametatex manual but not the
additions to \numexpr (I checked and : is mentioned but ; is missing).
\starttext
\startlines
\number\numexpr 5 + 2 \relax
\number\numexpr 5 - 2 \relax
\number\numexpr 5 * 2 \relax
\number\numexpr 5 / 2 \relax
\number\numexpr 5 : 2 \relax % new!
\number\numexpr 5 ; 2 \relax % new!
\stoplines
\stoptext
