BigInt Calculator

Work with numbers of thousands of digits without freezes or limits. All complex calculations are automatically accelerated by your device's GPU.

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.
