What will the code yield with the operation y = (2**100 + 1) - x, where x = float(2**100)?

In the expression y = (2**100 + 1) - x, where x = float(2**100), there is a loss of precision due to the characteristics of floating-point number representation in Python.

2**100 is an integer that Python can represent exactly. But when converting to float (a 64-bit floating-point number), the precision is limited, and the number is rounded.

As a result, float(2**100) is an approximate value, and 2**100 + 1 is an integer that is one greater. When calculating y, the following occurs:

x = float(2**100)
y = (2**100 + 1) - x
print(y)  # Will output 0.0

Because x has already been rounded to 2**100, adding 1 does not affect the floating-point value. Therefore, y will be equal to 0.0 due to the loss of precision.
