filib++, Expression Templates and the Coming Interval Standard
Reliable Computing, 15 (4):
312--320 (July 2011)Abstract
In this paper we investigate how a C++ class library can be improved
by the concept of expression templates. Our first result is a saving of
rounding mode switches which considerably increases the performance.
Our second result deals with handling the discontinuity flag that will
probably be decided to be raised whenever a function is called outside its
domain (loose evaluation). We discuss several alternatives and propose
an expression related flag that can be used in a thread safe manner.
Both results are reviewed with respect to the coming IEEE standard
for interval arithmetic.
