написать программу вычисления двоичного представления числа

[somewhere]

Прошу не винить за малофункциональность, но для решения именно этой задачи сгодиться. Формат числа немного изменился, теперь целая часть - 4 байта, остальные - дробная:

Код: Выделить всё

uses

type

  TBigBinNumber = array [0..24] of byte;

  TForm1 = class(TForm)
