In this lesson we will look at what a float is
and how to declare a float in Java.

As you see on this image, the floating-point number
is represented by two types in Java, namely:
The float and the double.

The float data type uses 32 bits to store a
floating-point number in the IEEE 754 standard format.

It's range is from 1.4 x 10‐⁴⁵ to 3.4 x 10³⁸.
Note, ranges include only magnitude.
It could be positive or negative.

All real numbers that end with f or F are called float literals.

Floats can be written both in decimal number format
or Scientific notation.

The wapper class for the foat is Float.

Let's look at some examples of declaring a float
