machine infinitesimal
A computing term referring to the smallest representable positive number in a floating-point system, essentially the machine epsilon's smallest magnitude. Rare outside technical contexts.
The machine infinitesimal is the smallest positive number that can be handled in floating-point arithmetic.
機械イプシロン (machine epsilon) is the difference between 1 and the next representable number, while 機械最小値 is the smallest positive normalized number.
Compound of 機械 (machine) + 最小値 (minimum value), a direct translation of the English computing term 'machine infinitesimal'.
