If we want to display a real number in decimal point representation (non-scientific format), the character
sequence becomes \%w.pf. The character sequence \%w.pf indicates that the associated data item should be
output as a floating-point number, in non-scientific format, which occupies a field of at least w characters,
and has n figures after the decimal point.\vspace{0.5cm}\\

enumerate但是和中的线条tikzpicture不在同一水平。我尝试使用，vspace{}但没有帮助。我希望我的文档如下图所示。
答案1
您应该将 MWE 保持在最低限度。我删除了那些不相关的包。对于边距，您的设置对我来说没有意义。我建议您使用几何包。我不认为minipage和在这里是必要的。您可以在里面tikzpicture使用输入这些数字和小数点。放在前面以使每个框具有标准和固定高度。并使用来自包定义一个命令来连续输入多个框。\hbox to length\fbox\strut\foreachtikz
以下是代码：
\documentclass[12pt]{article}
\usepackage{pgffor}
\def\baselinestretch{2.0}
%\setlength{\textwidth}{18cm}
%\setlength{\textheight}{21cm}
%\setlength{\evensidemargin}{-0.15cm}% doesn't make sense if you don't have twoside document. Your textwidth out of the paper
% use geometry package instead
\usepackage[margin=1in]{geometry}
%define a new command to type those numbers with frame for you.
\newcommand{\printf}[1]{%
\foreach \n in {#1}
{%
\fbox{\hbox to 0.8cm{\strut\hfil\n\hfil}}%
}%
}

带nicematrix包装

\usepackage{nicematrix}
\NewDocumentCommand{\printf}{ m }

\item
printf(``\%f”,12. 3456);\;$\to$ \printf{ 1 & 2 & . & 3 & 4 & 5 & 6 & 0 & 0 \\

\item
