maxvalue

Return largest value in array

Declaration

Source position: line 0

function maxvalue(

const data: array of Extended

):Extended; function maxvalue(

const data: PExtended;

const N: Integer

):Extended; function maxvalue(

const data: array of Integer

):Integer; function maxvalue(

const data: PInteger;

const N: Integer

):Integer;

Description

Maxvalue returns the largest value in the data array with integer or float values. The return value has the same type as the elements of the array.

The third and fourth forms accept a pointer to an array of N integer or float values.

Errors

None.

Example

program Example26;

{ Program to demonstrate the MaxValue function. }

{ Make sore integer is 32 bit}
{$mode objfpc}

uses math;

var i:1..100;
    f_array:array[1..100] of Float;
    i_array:array[1..100] of Integer;
    Pf_array:Pfloat;
    PI_array:Pinteger;

begin
  randomize;

  Pf_array:=@f_array[1];
  Pi_array:=@i_array[1];

  for i:=low(f_array) to high(f_array) do
    f_array[i]:=(random-random)*100;
  for i:=low(i_array) to high(i_array) do
    i_array[i]:=random(I)-random(100);

  Writeln('Max Float       : ',MaxValue(f_array):8:4);
  Writeln('Max Float   (b) : ',MaxValue(Pf_array,100):8:4);
  Writeln('Max Integer     : ',MaxValue(i_array):8);
  Writeln('Max Integer (b) : ',MaxValue(Pi_array,100):8);
end.
