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;

However, in other programming languages such as Javascript, Python we do not need to specify the datatype. Instead, we can just write,

var pi = 3.14; (in Javascript)
pi = 3.14 (in Python)
