Understanding Numeric Comparisons in Python: How Integer and Floating-Point Equality Works

When Python compares values of different numeric types (like an integer and a floating-point number), it first converts them to a common type to make the comparison meaningful and accurate. In the case of an integer and a floating-point number, the integer is implicitly converted to a float.

 

For example, let’s compare 10 with 10.0. In this example, the integer 10 is converted to the float 10.0, and since these two numeric values are the same, 10 == 10.0 evaluates to True. This behavior allows for more intuitive and practical numerical comparisons in Python, as it focuses on the numerical equivalence rather than the specific data type of the numbers involved.

>>> 10 == 10.0
True
>>> 
>>> 23 == 23.0
True
>>> 
>>> 23 == 23.0000001
False

Keep in mind that knowing how numbers are compared in Python can help you write better and more trustworthy code.
