abs

Prototype

function abs(a : integer) : integer;
Description

Function returns the absolute (i.e. positive) value of a.
Example 
res := abs(-12);  // res = 12

labs

Prototype

function labs(x : longint) : longint;
Description

Function returns the absolute (i.e. positive) value of long integer x.
Example 
res := labs(-2147483647);  // res = 12

min

Prototype

function min(a, b : integer) : integer;
Description

Function returns lower of the two integers, a and b.
Example 
res := min(123,67);  // function returns 67

max

Prototype

function max(a, b : integer) : integer;
Description

Function returns greater of the two integers, a and b.
Example 
res := max(123,67);  // function returns 123

rand

Prototype

function rand() : integer;
Description

Function returns a sequence of pseudo-random numbers between 0 and 32767. The function will always produce the same sequence of numbers unless srand is called to seed the start point.
Example 
while TRUE do
  res := rand();
end;

srand

Prototype

procedure srand(x : word);
Description

Function uses x as a starting point for a new sequence of pseudo-random numbers to be returned by subsequent calls to rand. No values are returned by this function.
