Fixed-Point Arithmetic

As with floating-point, fixed-point numbers are used to express real values of arbitrary range. Unlike floating-point numbers, their range is determined during compilation. This makes them an appealing candidate for representation as a class template.

John will present one such effort to produce a fixed-point library and share his experiences, including:

• how it has changed his notion of what an integer is;
• how it hasn't changed his notion of what a float is;
• how fixed-point has come to mean many things to many people;
• how you've lived so long without fixed-point arithmetic and
• how C++11 makes this stuff way easier.
