%
%\begin{abstract}
%This package helps user to write mathematical and  physical formulas
%-- their numerical values, their measurement units, their factors, their
%dimensions -- in a 
%scientific way (international mainly), by an elegant formatting.
%\end{abstract}
%\section{Introduction}
%
%\LaTeX{} is a powerful language, but to take advantage of it, to respect 
%its quality and to observe the discipline of matters that \LaTeX{} interacts with---it
%requires some devices.
%
%If you are interested in math and physics, here comes \textsl{isphysicalmath} inside \LaTeX{}
%as far as international scientific notation and formatting of formulas,
% quantities, numerical values, factors, dimensions, measurement units. \\
%
%The name \textsl{isphysicalmath} means either:
%\begin{itemize}
%	\item Physics is Math's daughter;
%	\item International System of units (SI) is observed.
%\end{itemize}
%
%\section{Conventions}
%To have a clear doc text, I'll not refer to physical quantities
%dimensions every times; for them, the measurement units 
%\textsl{isphysicalmath} acting is valid too.
%
%\section{Dependencies}
%\label{sec:dependencies}
%\textsl{isphysicalmath} has \textsl{xstring} package dependency.
%
%Internally,  it uses standard \LaTeX{} built-in commands like: \texttt{\textbackslash textnormal},
%\texttt{\textbackslash hspace\{\}}, \texttt{\textbackslash ,};
% however, it performs its activity in complex math environment too.
%\newpage
%\section{Usage}
%\label{sec:usage}
%\DescribeMacro{\ispm}
%
%\textit{hp.} It is a jolly command.
%The default setting consists in --- a $0.15\ispmone{mm}$ of space  and normal text rendering for a generic 'entity'.
%In other words  <\texttt{\textbackslash textnormal}> and <0.15mm> are the values of \texttt{\textbackslash ispm}
% variable. So, if you are a developer  you can modify this variable how and when you want.
% I use it for  generic ``entities''.  \\
%\textit{th.} Default setting: normal text rendering for a generic ``entity''.\\
%|\ispm|\marg{generic ``entity'' in place of argument}  \\ \\
%
%\DescribeMacro{\ispmone}
%
%\textit{hp.} You have only a measurement unit. \\
%\textit{th.} Horizontal space between measurement unit
%and numerical value,
%and normal text rendering for the measurement unit.\\
%|\ispmone|\marg{measurement unit in place of  argument}  \\ \\
% \DescribeMacro{\ispmtwo}
%
%\textit{hp.} You have two measurement units. \\
%\textit{th.} Horizontal space between the first measurement unit
%and numerical value, horizontal space  between the first measurement unit 
%and second measurement unit; normal text rendering for both measurement units.\\
%|\ispmtwo|\marg{the first measurement unit in place of the I argument}\marg{second
%measurement unit in place of II argument}  \\ \\
%\DescribeMacro{\ispmthird}
%
%\textit{hp.} You have three measurement units. \\
%\textit{th.} Horizontal space between the first measurement unit
%and numerical value, horizontal space between the first
%measurement unit and the second %measurement unit, horizontal space between
%the second measurement unit and  third measurement unit; normal text 
%rendering for all the measurement units.\\
%|\ispmtwo|\marg{the first measurement unit in place of the I argument}\marg{the second 
%measurement unit in place of the II argument}%
%|\ispmthird|\marg{third measurement unit in place of III argument} \\ 
% Or, e.g. if you have a fraction [see In-depth formatting' 
%(\autoref{subsec:inDepthFormatting})]:\\
%|\ispmone|\marg{the first measurement unit in place of the I argument (numerator)}
%|\ispmone|\marg{the second %measurement unit in place of the II argument (denominator)}
%|\ispmthird|\marg{third measurement unit in place of III argument} \\ \\

%\label{subsubsec:optionDc}
%\textsl{Usage}: \texttt{\textbackslash usepackage[dc]\{isphysicalmath\}} \\ 
%
%The code of this option is not mine, it already exists in \LaTeX{} literature, 
% I discovered it in \tiny\url{https://en.wikibooks.org/wiki/LaTeX}\normalsize. \\
%
%This option by \texttt{\textbackslash ispmc} changes dots in commas. It is useful for some users who don't 
%use scientific international notation. It is convenient for users who 
%respect scientific international notation, so they change dots
%in commas to select thousands and not to express numbers under the unit. \\
%
%e.g.
%\begin{center}
%	1.234 becomes 1,234
%\end{center}
%The code: 
%\begin{center}
%\begin{verbatim}
%\ispmc 1.234
%\end{verbatim}
%\end{center}
