Why do both the buffer and arithmetic types exist?

+

+
Conversions in the buffer types are explicit. Conversions in the arithmetic 
+types are implicit. This fundamental difference is a deliberate design feature 
+that would be lost if the inheritance hierarchy were collapsed.

+
The original design provided only arithmetic types. Buffer types were 
+requested during formal review by those wishing total control over when 
+conversion occurs. They also felt that buffer types would be less likely to be 
+misused by maintenance programmers not familiar with the implications of 
+performing a lot of arithmetic operations on the endian arithmetic types.

+

+
What is gained by using the buffer types rather than always just using the 
+arithmetic types?

+

+
Assurance than hidden conversions are not performed. This is of overriding 
+importance to users concerned about achieving the ultimate in terms of speed. 

+
"Always just using the arithmetic types" is fine for other users. When the 
+ultimate in speed needs to be ensured, the arithmetic types can be used in the 
+same design patterns or idioms that would be used for buffer types, resulting in 
+the same code being generated for either types.

What are the limitations of floating point support?
