ND1 is an advanced, programmable RPL/RPN calculator that can calculate with numbers, complex numbers, fractions, vectors, matrices, strings, images, algebraic expressions, and other types of objects.
Over 500 operators deliver a total of over 2,000 functions across all object types.
In many ways, ND1 is a modern day update to the RPL calculator line from HP (28, 48-50g).
Try ND0 before you buy, if you're unsure ND1 is for you.
There's plenty of documentation for ND1.
Please see the support website for full specs, a "Quick Tour", tutorials, reference documentation, and a discussion forum, where support can be found.
