p-adelic

A new look and a much more careful engine. • New app icon — the nested balls of ℤ₅, now in layered glass. • Newton polygons and factorization over ℚₚ are fixed; polynomials with mixed slopes now work. • Repeating blocks of every rational are now exactly right, and long runs of digits fold into tap-to-open pills. • Square roots at p = 2, non-squarefree radicands, cyclotomic digits and Galois conjugates are corrected. • exp, log, Artin–Hasse, factorials and Γₚ are exact to the chosen precision instead of stopping early. • No more crashes or freezes on extreme inputs (huge primes, exp(30), enormous exponents, deeply nested parentheses) — they are refused with a clear message. • The ∞ column shows the sign and integer part (√2 = 1.41421…). • Columns say why they are unavailable (needs extension, diverges here, not real) and offer the right action. • Friendlier errors, dimmed stale results, History entries you can reopen, Library search. • Proper math typesetting (ℚ₅, exponents), Dynamic Type, VoiceOver descriptions for every visualization, larger touch targets. • The keyboard no longer pushes the screen around, including on iPhone SE.
