Чтобы выполнить сложение чисел в формате с плавающей запятой, необходимо следовать определенным шагам. Давайте разберем задания 3 и 4 по порядку.

У нас есть два набора чисел, которые нужно сложить. Первые два числа: A1 и A2, а затем A3 и A4.

• A1 = +101,0011
• A2 = -0,001111

Первое, что нужно сделать, это привести числа к одному формату. В данном случае мы можем преобразовать A1 в десятичную дробь:

A1 = 101,0011 = 101,0011

A2 = -0,001111 = -0,001111

Теперь выполним сложение:

A1 + A2 = 101,0011 - 0,001111 = 101,0000,889

• A3 = -1,110101
• A4 = -10,011001

Теперь также приводим их к десятичному формату:

A3 = -1,110101 = -1,110101

A4 = -10,011001 = -10,011001

Теперь складываем:

A3 + A4 = -1,110101 - 10,011001 = -11,121102

Таким образом, результаты сложения в задании 3:

• A1 + A2 = 101,0000,889
• A3 + A4 = -11,121102

Теперь перейдем ко второму заданию, где числа представлены в научной нотации.

• A1 = -1,101 * 10^11
• A2 = 0,10101 * 10^101

Для сложения этих чисел, необходимо привести их к одному порядку. В данном случае, A2 имеет очень большой порядок, поэтому мы можем преобразовать A1:

A1 = -1,101 * 10^11 = -0,00000000001101 * 10^101

Теперь складываем:

A1 + A2 = -0,00000000001101 * 10^101 + 0,10101 * 10^101 = (0,10101 - 0,00000000001101) * 10^101 = 0,101009999989 * 10^101

• A3 = 10,10101 * 10^-110
• A4 = -1,01011 * 10^-10

Теперь также приводим их к одному порядку:

A3 = 10,10101 * 10^-110 = 0,00000000000000000000000000000001010101 * 10^-10

A4 = -1,01011 * 10^-10 = -0,0000000000000000000000000000000101011 * 10^-10

Теперь складываем:

A3 + A4 = (10,10101 - 1,01011) * 10^-10 =
