Ordinary calculators round. Constructive Calculator doesn't. It computes with constructive real numbers, an arbitrary-precision engine that keeps every result exact and hands you as many correct digits as you ask for. The rounding errors that quietly accumulate in ordinary calculators simply never happen. AS MANY DIGITS AS YOU WANT A pocket calculator stops at about 15 digits and rounds off the rest. Constructive Calculator keeps every result exact, so the digits a normal calculator throws away are still there. Swipe √2, π, or any answer to pull in tens, hundreds, or thousands more, computed on demand. SCIENTIFIC KEYPAD Trigonometry in degrees or radians and their inverses, exponentials and logarithms, powers and roots, factorials, percentages, the constants π and e, and the standard normal distribution, its CDF Φ and quantile Φ⁻¹, computed to the same arbitrary precision as everything else. BIG INTEGERS, IN FULL 52! (the number of ways to shuffle a deck) prints in full, all 68 of its digits, with no scientific-notation hand-waving. BUILT FOR CLARITY A running tape of recent calculations, locale-aware digit grouping, and copy at whatever precision you need. Constructive Calculator is an independent port of Hans Boehm's constructive-reals calculator, rebuilt natively for iPhone and iPad.
