## Description
|
|
<section id='description'>
|
|
We can store decimal numbers in variables too. Decimal numbers are sometimes referred to as <dfn>floating point</dfn> numbers or <dfn>floats</dfn>.
|
|
<strong>Note</strong><br>Not all real numbers can accurately be represented in <dfn>floating point</dfn>. This can lead to rounding errors. <a href="https://en.wikipedia.org/wiki/Floating_point#Accuracy_problems" target="_blank">Details Here</a>.
