**rpn**
- is a full-featured **math-oriented language** inspired by Hewlett-Packard **R**everse **P**olish **L**isp (**HP28S** user manual is provided as a reference), it includes at least **stack**, **store**, **branch**, **program**, **complex**, **real**, **test**, **trig** and **logs** commands
- is implemented as a **command-line calculator** for GNU/Linux
- brings powerfull calculation facilities on floating point numbers with __arbitrary precision__, provided by **GNU MP** and **GNU MPFR** libraries
- is a structured full-featured **math-oriented language** inspired by Hewlett-Packard **R**everse **P**olish **L**isp (**HP28S** and **HP48GX** user manual are provided as references), including **real**, **complex**, **stack**, **store**, **branch**, **program**, **test**, **trig** and **logs** commands and more to come
- is implemented as a **command-line calculator** for most popular Linux distributions
- brings powerfull calculation facilities on floating point numbers with __arbitrary precision__ provided by **GNU MP** and **GNU MPFR** libraries
- uses that so cool **reverse polish notation**
