Numbers in Python are of four types - integers, long integers, floating point and complex numbers.
Examples of integers are 2 which are just whole numbers.
Long integers are just bigger whole numbers.
Examples of floating point numbers (or floats
for short) are 3.23 and 52.3E-4.
The E notation indicates powers of 10. In this case,
52.3E-4 means
52.3 * 10-4.
Examples of complex numbers are (-5+4j) and
(2.3 - 4.6j)
