As many as you like; pi is an irrational number. That means that there are no two whole numbers that you can make into a fraction exactly equal to pi. It also means that if you start to calculate pi as a decimal it never ends and never recurrs. It just goes on forever.

A few years ago two Japanese people calculated pi to eight million places of decimals, which they then published in a book. It just never ends.

Update: in October 2011, pi to 10 trillion (and 50) digits was published. See link.

What is the decimal expansion of an irrational number?

A decimal expansion means to write out the base 10 digits of a number. Because irrational numbers do not have a closed form, the decimal expansion will always be an approximation. Consider the irrational number pi, which has the following decimal expansion: 3.14159265... Of course there are more digits to pi than that, which is denoted by the "...". It is sadly impossible to list ALL of the digits of an irrational numbers, since if there were a finite number of digits, you could express it as a fraction, which would not be irrational.


What is pi in numbers?

Pi can be estimated to various levels of accuracy:3.143.14163.14159The value pi is a type of number known as an irrational number which simply means it cannot be written as a fraction. Furthermore it is not algebraic which means it is not the root of a non-zero polynomial. Numbers that are not algebraic are known as transcendental numbers. By definition Pi is the circumference of a circle divided by its diameter.There are an infinite number of possible digits to which pi can be computed: it does not terminate or repeat. To date it has been computed to as many as 10 trillion digits. For ordinary mathematics, using anything more than 10 places would only negligibly improve the accuracy of the calculations (to 10 decimal places, pi is 3.1415926536).

What are the most digits of the Square root of pi?

The square root of pi is an irrational number, meaning it has an infinite number of digits after the decimal point. It is typically rounded to a limited number of digits for practical use, such as 3.1416. However, if you are looking for the actual number of digits in the square root of pi, it would be infinite.

How many digits are there in all numbers inclusive from 1 to 1000?

Infinitely many. The number pi , for example, is between 1 and 1000 and, since pi is a transcendental number, it contains infinitely many digits. Plus, there are all the irrational numbers - each with infinitely many digits, and all the rationals with recurring decimals - again with infinitely many digits.
