v2.3.0

This release completes the scientific calculator and adds a standard one beside it.

📝 Changelog

• Every function key computes: the keys on the operator panels that did not compute yet now all do, measured against a Casio fx-87DE X: sec, csc and cot with their inverse and hyperbolic forms, floor, ceil, Int and Intg, GCD, LCM, nPr and nCr, Ran#, RanInt# and RndFix, the decimal prefixes, the mixed fraction key, division with remainder (17÷R5 is Q=3, R=2), Pol and Rec, FACT for the prime factors, and angles in degrees, minutes and seconds with dms and deg. A new Calculus panel adds Σ, Π, the integral and the derivative, with x as their variable (#24, #28, #29, #30, #33).
• Exact results: a result stays exact the way it does on a Casio: fractions, square roots with the squares pulled out, sums of two roots and multiples of π, so sin 45° is √2/2 and 0.1+0.2 is 3/10. A result opens in its exact form, and S⇔D cycles it through the exact form, the recurring decimal with a bar over its period and the plain decimal (#23).
• Calculator settings: the settings page gains the angle unit, exact or decimal first, improper or mixed fractions, Norm 1 and Norm 2 or Fix and Sci with 0 to 9 digits, decimal prefixes, the decimal mark and digit grouping (#20).
• Standard calculator: a new Standard page with a plain pocket calculator pad; the existing calculator is now called Scientific. Every page keeps its formula and result when you switch away and back (#36).
• The settings show the app version, the third-party libraries and a link for feedback (#37).
• Fixed very small trigonometric results losing digits, and tan giving a number at π/2 in radians but a Math ERROR just short of 90° (#26).
• Fixed the currency lists sometimes opening away from their button (#2).
