- n. The inorganic orthophoshate ion; -- a symbol used in biochemistry.
- n. A mass of type confusedly mixed or unsorted.
- n. A Greek letter (Π, π) corresponding to the Roman letter p.
- n. The letter π, Π, as used to denote the number or quotient approximately expressing the ratio of the circumference of a circle to its diameter; also, the quotient or the ratio itself. The value of the quotient pi, to twenty decimal places, is 3.14159265358979323846 (see note). The number pi is an irrational number, i.e. it cannot be expressed as the quotient of two integers. It is also a transcendental number, i.e. it cannot be expressed as a root of an algebraic equation with a finite number of terms; and from this fact follows the impossibility of the quadrature of the circle by purely algebraic processes, or by the aid of a ruler and compass.
- transitive v. To put into a mixed and disordered condition, as type; to mix and disarrange the type of.

I have already mentioned that the dwellings of the islanders were almost invariably built upon massive stone foundations, which they call pi-pis.
You could slice up history into what he called pi cycles, each lasting exactly three thousand one hundred and forty-one days, or 8.6 years.
You will notice that this function is not tail recursive, indeed the last operation to happen in the second branch is not a direct call to fact, but a call to the multiplication operator (*) with arguments n and fact(n - 1). (see my article on 1st Class Function to know how to make this function tail recursive) keyword allows you to bind symbol/names to values. for example let pi = 3.14 will bind the value 3.14 to the name pi.
UPDATE: The same quibble applies to the CNN story, which says Mathematicians know that pi is irrational — it cannot be represented as one number divided by another — and transcendental, meaning it is not algebraic.
A proof of the nonexistence of any particular finite sequence of digits in its decimal expansion would have as a corollary that pi is not normal.
OperationCounterstrike: It has been neither proven nor disproven that pi is normal.
