# Python Floating Point Numbers
Some general information about floating point numbers and how they work in Python, can be found <a href='https://docs.python.org/3/tutorial/floatingpoint.html' target='_blank' rel='nofollow'>here</a>.
Nearly all implementations of Python follow the IEEE 754 specification: Standard for Binary Floating-Point Arithmetic. More information found on the <a href='http://grouper.ieee.org/groups/754/' target='_blank' rel='nofollow'>IEEE site</a>.
## Float objects using floating point literals
Float objects can be created using using <a href='https://docs.python.org/3/reference/lexical_analysis.html#floating-point-literals' target='_blank' rel='nofollow'>floating point literals</a>:

## Float objects using float constructors
The <a href='https://docs.python.org/3/library/functions.html#float' target='_blank' rel='nofollow'>`float`</a> constructor is another way to create `float` objects.
Creating `float` objects with floating point literals is preferred when possible:
