### Round

#### Synopsis

    function Round (x: Real): Integer;

#### Description

`Round` returns the nearest integer to `x`. The result is of type integer. In the case of equidistance, the result is machine-dependent (or depends on the behaviour of the processor).

#### Conforming to

`Round` is defined in ISO 7185 Pascal and supported by all known Pascal variants.

#### Example

    program RoundDemo;
    var
      Foo: Real;
    begin
      Foo := 9.876543;
      WriteLn (Round (Foo));  { Prints 10 }
      Foo := 3.456789;
      WriteLn (Round (Foo));  { Prints 3 }

      WriteLn (Frac (12.345) : 1 : 5);  { 0.34500 }
      WriteLn (Int (12.345) : 1 : 5);  { 12.00000 }
      WriteLn (Round (12.345) : 1);  { 12 }
      WriteLn (Trunc (12.345) : 1);  { 12 }

      WriteLn (Frac (-12.345) : 1 : 5);  { -0.34500 }
      WriteLn (Int (-12.345) : 1 : 5);  { -12.00000 }
      WriteLn (Round (-12.345) : 1);  { -12 }
      WriteLn (Trunc (-12.345) : 1);  { -12 }

      WriteLn (Frac (12.543) : 1 : 5);  { 0.54300 }
      WriteLn (Int (12.543) : 1 : 5);  { 12.00000 }
      WriteLn (Round (12.543) : 1);  { 13 }
      WriteLn (Trunc (12.543) : 1);  { 12 }

      WriteLn (Frac (-12.543) : 1 : 5);  { -0.54300 }
      WriteLn (Int (-12.543) : 1 : 5);  { -12.00000 }
      WriteLn (Round (-12.543) : 1);  { -13 }
      WriteLn (Trunc (-12.543) : 1);  { -12 }
    end.
