## Description

Minvalue returns the smallest 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 Example31;

    { Program to demonstrate the MinValue function. }

    { Make sure 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;

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