About BigInt Calculator (Viktor Pobedria)
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: × ÷ : ,
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 math 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.
