Description

Format replaces special formatting substrings in a given string s with the data provided by the given array data, they are replaced in the order that they are defined in s. The format of each substring is given as "%[Index:][-][Width][.Precision]Type".

Type Indicators

• %d: An integer value
• %e: Scientific notation
• %f: Fixed point notation
• %g: Regular notation
• %m: Currency notation
• %n: Floating point notation
• %s: A string value
• %u: Unsigned integer notation
• %x: Hexadecimal notation

Example 1^[1]

begin
  WriteLn(Format('Decimal          = %d', [-123]));
  WriteLn(Format('Exponent         = %e', [12345.678]));
  WriteLn(Format('Fixed            = %f', [12345.678]));
  WriteLn(Format('General          = %g', [12345.678]));
  WriteLn(Format('Number           = %n', [12345.678]));
  WriteLn(Format('Money            = %m', [12345.678]));
  WriteLn(Format('String           = %s', ['Hello']));
  WriteLn(Format('Unsigned decimal = %u', [123]));
  WriteLn(Format('Hexadecimal      = %x', [140]));
end.

Output:

Decimal          = -123
Exponent         = 1,23456780000000E+004
Fixed            = 12345,68
General          = 12345,678
Number           = 12.345,68
Money            = € 12.345,68
String           = Hello
Unsigned decimal = 123
Hexadecimal      = 8C

Example 2

begin
  WriteLn(Format('%.2f', [12345.6789]));
  WriteLn(Format('%.10d', [12345]));
  WriteLn(Format('%10d', [12345]));
end.

Output:

12345,68
0000012345
     12345
