number of digits to be retained after the decimal point
Online PI(π) query tool, supports querying the PI value of the specified number of digits after the decimal point, and supports querying up to 1,000,000 (one million) digits. The result can be copied and downloaded.
- Pi, the ratio of a circle's circumference to its diameter, i.e., Pi = Circumference ÷ Diameter, is also equal to the ratio of a circle's area to its radius squared, i.e., Pi = Circle Area ÷ Radius², and is usually denoted by the Greek letter π.
- Pi is a mathematical constant that is prevalent in mathematics and physics, and is a key value for the accurate calculation of the circumference of a circle, the area of a circle, the volume of a sphere, and other geometric shapes. In analytics, π can be strictly defined as the smallest positive number x that satisfies sin(x) = 0.
- Pi is an irrational number, i.e., an infinitely irreducible decimal. In everyday life, 3.14 is usually used to represent pi for approximate calculations. The nine-digit decimal number 3.141592654 is sufficient for general calculations. Even engineers or physicists who want to perform more sophisticated calculations need only take the value to a few hundred decimal places at most.
- This tool supports displaying pi to a maximum of 1000000 (one million) decimal places of the exact number of digits, when you fill in the specified number of digits, the specified number of digits after the number of digits are truncated directly, will not be rounded up.
