Floating-point are numbers with floating decimal points.
Floating-point, as the name implies, are numbers that contain decimal points that can float left or right.
In programming, floating-point is used to represent fractions. Numbers such as 1/2, 5/7, -100/3 can be represented in floating-point as 0.5, 0.71428, -33.33.
Often the keyword 'float' is used to declare a variable that stores floating-point numbers.
For example, in C and Java
float pi = 3.14;
pi = 3.14 (in Python)
