Number axis with interval symbols

Based on one of the similar previous answer (which I temporary can't find):

documentclass[tikz, margin=3mm]{standalone}
usetikzlibrary{arrows.meta}

begin{document}
begin{tikzpicture}
  draw (-3,0) -- (3,0);
  draw (0,2pt) -- (0,-2pt) node[below=2mm] {$0$};
  draw[{Bracket[width=4mm]}-{Bracket[width=4mm]}] 
    (-2,0) node[below=2mm] {$-1$} -- ( 2,0) node[below=2mm] {$ 1$};
  draw[{Parenthesis[width=4mm]}-{Parenthesis[width=4mm]}]
    (-1,0) node[below=2mm] {$-frac{1}{2}$} -- (1,0) node[below=2mm] {$ frac{1}{2}$};
end{tikzpicture}
end{document}
