Lesson 2. Integer and float numbers




4/10. Very big and very small numbers

You can write floats with very big or very small absolute values using the scientific notation. Eg., the distance from the Earth to the Sun is 1.496·1011 meters, or 1.496e11 in Python. The mass of one molecule of water is 2.99·10-23 grams, or 2.99e-23 in Python.

Hint

A billion is 109, so you can print 3.9e9 

# It is well-known that life on Earth
# appeared approximately 3.9 billion years ago.
# You can check it on Wikipedia, for example.
# Assign this value in the scientific
# notation to any variable,
# and then print that variable.
