看来 \mathds 和 \mathbbm 仅针对数字一到九进行定义,数学模式中是否有一些字体适用于零?
答案1
这是我在系统上能找到的所有字体。随便用用吧。
% arara: pdflatex
\documentclass{article}
\usepackage{bbold} % all ten digits with \mathbb
%\usepackage{mathbbol} % all ten digits with \mathbb
%\usepackage{mbboard} % not working here, but should have your digits with \mathbb
%\usepackage{bbm} % just 1 and 2 with \mathbbm, \mathbbmss, and \mathbbmtt
%\usepackage[sans]{dsfont} % just 1 with \mathds with and without sans option
\begin{document}
$\mathbb{0123456789}$
\end{document}
