There are 3 special types out there that are considered numbers but don’t actually behave as numbers.
These are the positives and negatives of the concept of infinity.
They can both be considered the same since a negative infinity translates into the concept of infinity as well.
This is another special type that is also considered a number at the same time.
NaN stands for ‘Not a Number.’
Some examples of NaN include dividing Zero (0/0) by itself or subtracting Infinity (infinity – infinity) by itself.
