A calculator for those who need more than standard precision. Works with integers and decimals of arbitrary size — no rounding, no overflow, no lost digits. Heavy operations are accelerated on the GPU via Metal, so even multiplying numbers thousands of digits long stays fast. Features - Addition, subtraction, multiplication, division - Powers and square roots (0.5, 1.5, 2.5…) - Parentheses and correct operator precedence - Three independent tabs M1, M2, M3 for parallel work - Live calculation progress and elapsed time - Cancel long operations at any moment - Copy expression or result with one tap - Alternative symbol support: × ÷ : , GPU acceleration The interpreter chooses between CPU and GPU based on expression complexity and auto-tunes itself to your device. This delivers a noticeable boost for operations on numbers with hundreds or thousands of digits. Who it's for - Students and maths teachers - Developers working with cryptography and large primes - Number theory researchers - Anyone hitting the limits of ordinary calculators No ads, no trackers, no accounts. Works on smartphone, tablet, and computer.
