Lookup English Definition:

pi    : [p'ɑɪ]
Pi \Pi\ (p[=e]` [imac]"), n. (Chem.)
The inorganic orthophoshate ion; -- a symbol used in
biochemistry. [acronym]

Pi \Pi\ (p[imac]), n. [See {Pica}, {Pie} magpie, service-book.]
A mass of type confusedly mixed or unsorted. [Written also
[1913 Webster]

Pi \Pi\ (p[imac]), n. [Gr. pi^.]
1. A Greek letter ([Pi], [pi]) corresponding to the Roman
letter {P}.
[Webster 1913 Suppl.]

2. Specifically: (Math.) The letter [pi], [Pi], 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.
[Webster 1913 Suppl. PJC]

displayed below.
The digits are arranged as five sets of ten digits per
line in twenty lines, proceeding left to right in each
