Detection of whether a result of a floating point operation is safe. In one embodiment, an integrated circuit may include a processor containing an execution core and a data cache. The locking element in the casing is mounted about an axis so as to be pivotable from a retaining position into a release position and back. The devices are preferably ribbed on the inside surface, and are made to releaseably interlock when used plurally. The main segment is a series of repeater sections with negative dispersion, while the compensation segment is a single repeater section with positive dispersion. The systemmethod is configured to allow any number of CORS to share DCDS using a Content Collaboration Platform while retaining complete DCDS integrityretrieval control using a hierarchical Access Rights and Control List to prevent CORS from uncoordinated DCDS modification and prohibiting local maintenance of DCDS copies after the expiration of a CORS Data Access Session.
