```

#### Description

#### Example

```     program IntDemo;

begin
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.
