## Answers to Questions (FAQ)

### What is the number Tau? (Definition)

The Tau number (τ) is a mathematical constant that represents the ratio between the circumference of a circle and its radius. It is an alternative to the number π (pi), and its approximate value is 6.2831853.

### How to find a number in Tau?

Detecting a number within the decimals of Tau requires systematically traversing all the decimals in their sequence, there is no possible alternative. It remains impossible to anticipate in advance a specific number and its position within $\tau$.

Example: 8 is is position 2 and 5 (and many others)

For dCode, in the number 6.2831, the first decimal 2 is at position 1. However, some software treats it as position 0 (due to computers counting from 0), while others place it in position 2 (taking the number 6 before the comma like position 1).

### What are the names for Tau?

Also known as Al-Kashi's constant, Tau is often replaced by $2\pi$, it is sometimes called twin or big brother of Pi ($\pi$).

### How many digits are there in Tau decimals?

There are an infinity of decimals in the constant τ = 6.2831853… Supercomputers are constantly looking for new decimals. dCode is familiar with Tau decimal places up to 1000000 decimal places (one million decimal places of Tau).

### What is the difference between Tau and Pi?

Tau is equal to 2 times Pi: $$\tau = 2 \pi$$

### Why use Tau instead of 2 Pi?

Tau is sometimes used as a useful abbreviation in concepts related to circles and trigonometry. Some educators feel that using Tau simplifies formulas and makes concepts more intuitive for students.

### Why is there a debate about using Tau versus Pi?

The debate between the use of Tau and Pi largely stems from the personal preference of mathematicians and the perceived advantages of each constant. Some consider Tau to be more natural for calculations related to circles, while others prefer the tradition and familiarity of Pi.
