Understanding Types of Software Bugs

Learn about the different types of software bugs.

We'll cover the following

Types of bugs

There are many different ways we can classify bugs. Here, we will look at some common types, see what they are, and see what they can look like.

Arithmetic bugs

Arithmetic bugs, as the name suggests, have to do with arithmetic operations. There are a few things we should look out for, as outlined below.

Division by zero

One thing to look out for is division by zero. This is not only related to computersâ€”we can also never perform a division operation where the divisor is zero. In mathematics, dividing by zero has no meaning, because if we do 6 / 2, we will get 3. If we multiply 3 and 2, weâ€™ll get 6 back. But if we take 6 / 0, there is no number we can multiply by zero to get back to 6.

This might seem simple enough, but sometimes, it happens anyway, especially when weâ€™re working with variables. Letâ€™s assume that we have two variables that get their value somewhere in our application, like this:
