Floating-Point Data Types

This section describes value ranges and storage space sizes of floating-point data types: float and double.

Java supports 2 floating-point data types: byte, float and double.

From the data value point of view, each floating-point data type can represent the following real number values:

From the data storage point of view, each floating-point data type is stored its values differently:

For more information, read the 'IEEE 754 Standards - "float" and "double"' tutorial from my "C# Tutorials - Herong's Tutorial Examples" book at herongyang.com/C-Sharp/Floating-Point-Data-Type-IEEE-754.html.
