About π
Pi (π) is the ratio of a circle's circumference to its diameter; it is an irrational and transcendental number.
- π ≈ 3.14159265358979323846...
- π is irrational — its decimal expansion never repeats
- π is transcendental — it is not the root of any polynomial with integer coefficients
- As of 2024, π has been computed to 105 trillion decimal places
Usage Instructions
Features
The Pi query tool uses Machin's formula with big-integer arithmetic to compute π to a specified number of decimals (1-1000), with quick lookup buttons and a reference of basic π properties.
Steps
Enter the number of decimal places (1-1000) → Click "Query" to view the corresponding decimals of π → Click "Copy Result" or use the quick lookup buttons; the table at the bottom shows the approximation and base representations of π.
Notes
π is computed in real time by a local algorithm; more digits take longer. π is irrational and transcendental, and its decimal expansion never repeats.
