English
For every prime p, the map Rat.padicValuation p: ℚ → ℤᵐ⁰ is surjective; every value in the target occurs as the p-adic valuation of some rational number.
Русский
Для каждого p простого числа отображение Rat.padicValuation p: ℚ → ℤᵐ⁰ сюръективно; любая величина достигается p-адической оценкой некоторого рационального числа.
