In reply to perumallatarun:

Random ‘real’ number can be selected by randomizing non-integral variable and passing it to built-in SV 1800-1200 Mathematics Function which gives real number. Input to built-in math function should be controlled as per desired result.
E.g.

// Purpose: Randomize non-integer(real, shortreal, realtime) values
module top;
  class non_integer;
    rand int in;
    real in1;
    
    constraint c_in {in > 1;}


    function void post_randomize();
      in1 = $ln(in);
    endfunction // post_randomize

  endclass // non_integer

  initial
  begin
    non_integer ni;
    ni = new();

    if(!ni.randomize())
    begin
      $display("Randomize failed");
    end
    else 
    begin
      $display("Non Real Number: in = %d", ni.in);
      $display("Real Number: in1 = %f", ni.in1);
    end
  end
endmodule // top
