4.1.2.1 Format

Format function

Prototype:	function Format(s: string; const args: array of const): string;
Description:	The Format function is used to easily construct a formatted string from several values of different types. "s" is the formatting string; it is basically a template for the output string which contains special patterns (format strings) replaced in the output string with the formatted values taken from the "args" array. Basic format strings are "%d" for integer values, "%s" for string values and "%f" for floating point values. An X.Y modifier can be placed between the "%" sign and the letter specifying the data type. X specifies the formatted width of the value (0 stands for the minimal width) and Y specifies the number of decimal places (e.g. %0.5d, %3.2f etc.)
Syntax:	Format(String,Arguments);
	Part	Description
	String	A string template containing special patterns to be replaced by actual values
	Arguments	An array of values used to replace a special patterns in the template specified by String
Return value:	A formatted string.

Example:

var
  ID: integer;
  Height: double;
  s, Species: string;

begin
  ID := 1;
  Height := 8.5;
  Species := 'pinus pinea';

  s := Format('Species of the tree with ID=%.3d is %s and the height of tree is %0.2f [m]', [ID, Species, Height]);

  ShowInformation(s);        

end.
