This is a personal note by Taku. Never bother with it.

Elementary Theory of Analytic Functions of One or Several Complex Variables (Paperback) Special Functions and Their Applications

$x^{2}={x \choose 1}+2{x \choose 2}={x+1 \choose 2}+{x \choose 2}$ where x is real.

P5 is a programming language designed by me (Takuya Murata) for use in describing the semantics of a usual programming language and algorithms and data structures. Design principles are:

Little happens implicitly.
The language is not necessarily practical for application or system programming.
Don't work on what you dislike; work on what you like or work very hard so you can work on what you like.

There is not difference between a selection control flow (a switch statement in C) and an associative array.

map = 'There is an ' +.each [0: 'even'; 1: 'odd'] + ' number of people on the Earth';
print map[get ('the population of the Earth') mod 2]

is equivalent to:

map = print 'There is an ' +.each [0: 'even'; 1: 'odd'] + 'number of people on the Earth';
map[get ('the population of the Earth') mod 2]

0: print '10 + 13 = '
1: goto 4
2: push 13
3: goto 6
4: push 10
5: goto 1
6: add
7: print

s = [0 ... ];

def b0_1
{
  print '10 + 13 = ';
  b4_5;
}

def b2_3
{
  s[1] := 13;
  b6_7;
}

def b4_5
{
  s[0] := 10;
  b2_3;
}

def b6_7
{
  s[0] := s[0] + s[1]
  print s[0];
  halt;
}
