What Are the Hyperreals?A nonzero number ε is defined to be ., or ., if.In this case the reciprocal . will be ., or simply ., meaning that . Conversely, if a number ω has this last property, then . will be a nonzero infinitesimal.

Ultrapower Construction of the HyperrealsLet ℕ = {1, 2,…}, and let ℝ. be the set of all sequences of real numbers. A typical member of ℝ. has the form . = 〈.,.,.,… 〉, which may be denoted more briefly as 〈.: . ∈ ℕ〉 or just 〈.〉.
