Not exactly a benchmark, and it may be neither short nor sensible, but I bodged up a version of Kahan's Paranoia to run under Plan 9 a while back. The summary was as follows: No failures, defects nor flaws have been discovered. Rounding appears to conform to the proposed IEEE standard P754, except for possibly Double Rounding during Gradual Underflow. The arithmetic diagnosed appears to be Excellent! The exception was a "denormalized operand" exception in the search for overflow threshold.
