(N:number):boolean;

Function

EVEN function returns TRUE if number N is not odd.

See also ODD function, below.

(N:number):boolean;

Function

ODD function returns TRUE if number N is odd.

See also EVEN function, above.

(var X [ ; N: number] );

Procedure

X is a number-type variable.
N is an optional number-type expression.

If N is specified then X increments by N; that is, INC(X, N) corresponds to the statement X := X + N.
If N is not specified then X increments by 1; that is, INC(X) corresponds to the statement X := X + 1.
Note that INC generates optimized code and is especially useful in tight loops.

See also DEC procedure, below.

(var X[ ; N: number] );

Procedure

X is a number-type variable.
N is a number-type expression.

If N is specified then X decrements by N; that is, DEC(X, N) corresponds to the statement X := X - N.
If N is not specified then X decrements by 1; that is, DEC(X) corresponds to the statement X := X - 1.
Note that DEC generates optimized code and is especially useful in tight loops.

See also INC procedure, above.

(A,B: number): number;

Function

MIN returns the lower of the two values A and B; negative values are smaller than zero. Thus:

When	MIN returns	Example
When	MIN returns	A	B	MIN
A>B	B	2	1	1
A<B	A	-2	-1	-2
A=B	B	2	2	2

See also MAX function, below.

(A,B: number): number;

Function

MAX returns the higher of the two values A and B; negative values are smaller than zero. Thus:

When	MAX returns	Example
When	MAX returns	A	B	MAX
A>B	A	2	1	2
A<B	B	-2	-1	-1
A=B	B	2	2	2

See also Min function, above.

[Range: number]:number;

Function

RANDOM function returns a random number within the range:
0 <= X < RANGE.

(N:number):string;

Function

INTTOSTRING converts number N to string representation.

Rotate example, Column example
