# Overview

LaTeX is a powerful language, but to take advantage of it, to respect its quality \
and to observe the discipline of matters that it interacts with: it requires some \
devices.

If you are interested in the form of math and physics, here comes `isphysicalmath` \
inside LaTeX; as far as international scientific notation and formatting of formulas, \
quantities, numerical values, factors, dimensions, measurement units.

So, isphysicalmath` package helps user to write mathematical and physical contents, \
according to the scientific notation (international mainly), in an elegant way.


# Dependencies

`isphysicalmath` has xstring package dependency, but you don’t need to specify \
it in your document preamble.

Internally, it uses standard commands like: \textnormal, \hspace{}, \,; however, \
it performs its activity in complex math environment too.


# Documentation
