is pi considered a real number?
17806
Pi is an irrational number, which means that it is a real number that cannot be expressed by a simple fraction. That's because pi is what mathematicians call an "infinite decimal" — after the decimal point, the digits go on forever and ever.

Reals: any number that is rational or irrational - any number on the number line. As you can see, −12 is an integer, but it is also a rational number because it can be made into a fraction: −121 and it is real because it can be found on the number line.

The real numbers are a subset of the complex numbers, so zero is by definition a complex number ( and a real number, of course; just as a fraction is a rational number and a real number). If we define a pure real number as a complex number whose imaginary component is 0i, then 0 is a pure real number.

Recall that pi is irrational, whose approximate value is 3.14. Therefore, 1/pi will be irrational and clearly 0 < 1/pi < 1. It should be obvious that 6 + 1/pi is irrational and it lies between 6 and 7.

The simplest approximation for Pi is just 3. ... In the past, many math books listed Pi as 22/7. Again, this is just an approximation but it is better than the value of 3 (actually 22/7 is closer to Pi than just writing 3.14).

Jorge is correct in saying that imaginary numbers are neither rational or irrational. If you are referring to complex numbers, they are of the form b + c*i, which b and c are real numbers. If c = 0, then the complex number is just the real number, b, which may or may not be irrational.

Real numbers are, in fact, pretty much any number that you can think of. This can include whole numbers or integers, fractions, rational numbers and irrational numbers. Real numbers can be positive or negative, and include the number zero.

It is an irrational number. A number is rational if it can be expressed as a quotient of 2 integer numbers. Number π2 cannot be expressed as a quotient of integers, so it is an irrational number.

Yes. Every real number is necessarily a rational number or an irrational number.
