increment; step value
Technical term used in computing, engineering, and mathematics for the smallest discrete change or step size in a sequence or scale.
In this program, calculations are performed with the increment set to 0.1.
The step value on the graph is too fine, making it hard to read.
Compound of 刻み (きざみ, 'notch' or 'step') and 値 (ち, 'value'). The exact historical derivation is uncertain, but the term is conventionally associated with discrete increments in technical fields.
