No sign bit
Negation flips each digit without carries, the range is symmetric, and signed and unsigned instruction variants are unnecessary.
An emulation platform for ternary computers.
Ternaria builds the software stack for machines that compute in base three: an emulator, a programming language, numerical libraries, and machine learning experiments on ternary hardware.
The emulator runs programs; the rest is design.
Balanced ternary
Digits are −1, 0 and +1. The word is 27 trits, about 42.8 bits.
Truncation rounds to nearest
Discarded digits are worth at most half a unit in the last place, and exact ties cannot occur, so there are no rounding modes.
Comparison returns one value
A comparison has three outcomes and a trit has three states, so one instruction returns less, equal or greater.
A third logical value
The middle state carries missing data directly, as SQL's
NULL does.
