The module p_adic_abs contains functions to calculate the p-adic absolute-value of a rational number.

The function p_adic_abs takes a prime $p$ and a rational number $x$ as its arguments and returns the p-adic absolute value $|x|_p$ as a float.

The float can be converted to an integer ratio with the fractions package.

Example:

import p_adic_abs
p = p_adic_abs.p_adic_abs(5, 200)
0.008

from fractions import Fraction
Fraction(p).limit_denominator().as_integer_ratio()
(1, 125)
