In Python, the float type represents floating-point numbers and follows the IEEE 754 standard for floating-point arithmetic. The size of a float in Python is typically 64 bits or 8 bytes.
my_float = 3.14
In Python, you can declare a float variable simply by assigning a value with a decimal point to it.
The size of a float object in Python can vary depending on the Python implementation and the underlying platform. However, in most Python implementations, including CPython (the reference implementation), the size of a float object is typically 24 bytes.
Python float size example
You can use the sys module to check the size of a float object in your Python environment. Here’s an example:
import sys
float_size = sys.getsizeof(float())
print(f"Size of a float object: {float_size} bytes")
Output:
Keep in mind that the reported size may vary slightly between different Python implementations and platforms.
