WebSep 26, 2024 · The machine epsilon is denoted by ϵ . With rounding to nearest, the machine epsilon can be determined by the following formula: ϵ = 1 2 β 1 − p. where β is the base and p is the precision (i.e. number of significant digits). For β = 10 and p = 3 since 1 + 0.005 = 1.01 > 1, ϵ = 0.005 = 1 2 10 1 − 3 = 1 2 β 1 − p.
