+# Floating Point Numbers
+
+Floating point numbers are numbers that have a decimal point in them. They are used to represent real numbers. For example, 3.14 is a floating point number. 3 is not a floating point number because it does not have a decimal point in it.

+Big endian is the most common type of endianness. In this type, the most significant byte is stored at the lowest memory address. This means that the most significant byte is stored first and the least significant byte is stored last.

+
+Endianess is the order in which bytes are stored in memory. The two most common types of endianess are big endian and little endian. Big endian stores the most significant byte first, while little endian stores the least significant byte first.
