<h2>Command-line calculator</h2>
<p>This is an <em>rpn</em> calclulator with a maximum stack size of 5. It has full support for real and complex numbers
and will calculate summary statistics for a set of reals of real pairs. Spaces are important since they are used
to distinguish tokens.</p>
<h2>Building</h2>
<p>The source code is written in <em>Fortran</em>. The only compilers I've found that will build it are <em>ifort</em> and <em>ifx</em> from Intel's
OneApi suite. Makefiles are provides for GNU make (Linux) and nmake (Windows).</p>
