# HP50g Full Specifications

Calculating Environments

\* RPL-style RPN (Reverse Polish Notation)

\* EOS-style algebraic

\* Equation Writer (textbook-style input)

\* Stack display shows 7 lines by default, but it can be increased to 8 or 9 by shrinking or removing the header

Programmability

\* Five built-in programming languages: User RPL, HP Basic, System RPL, Saturn assembly, ARM assembly

\* Compilation and decompilation of code built-in, along with limited debugging support

\* Programmable in C using a PC and third-party software (HPGCC)

\* Built-in tools for hacking the internal operating system and creating system libraries

\* Full access to all built-in commands, including all stack operations, branching, testing, graphics, time, input and output
