Noun
incrementation (countable and uncountable, plural incrementations)
The act or process of incrementing.
This machine performs incrementation by one of a number in unary encoding: It loops over any number of "1" cells and appends an additional "1" at the end. Source: Internet
In most of them, each register can hold a natural number (of unlimited size), and the instructions are simple (and few in number), e.g. only decrementation (combined with conditional jump) and incrementation exist (and halting). Source: Internet
