Задача 1.
Составьте программу нахождения наименьшего из двух чисел a и b.

Задача 2.
Даны числа x, y, z. Возвести в куб те числа, значения которых отрицательны.

Function min(a As Double, b As Double) As Double

Dim a1 As Double, b1 As Double, ab As Double, z As Integer

z = Sgn(Abs(a - b))

a1 = Abs(a)

b1 = Abs(b)

ab = a1 + b1

a1 = a + ab

b1 = b + ab

min = a * Sgn(Int(b1 / a1)) * z + b * Sgn(Int(a1 / b1)) * z

End Function

Function negcube(x As Double, y As Double, z As Double)

Dim i As Double

i = (x - Abs(x)) / 2

x = x + (x * x - 1) * i

i = (y - Abs(y)) / 2

y = y + (y * y - 1) * i

i = (z - Abs(z)) / 2

z = z + (z * z - 1) * i

End Function
