Abstract
The anomaly handling facility provides a system for controlling conversion, detecting anomalies, providing analysis of anomaly content in an array of floating-point elements, and preserving reconstruction data to recover value accuracy typically lost when anomalies are encountered during conversion. Although the preferred embodiment specifically handles anomalies relative to the commonality of value representation by both IBM ESA/370 hexadecimal floating-point notations and ANSI/IEEE 754-1985 binary floating-point stand notations, the systematic design provided by the disclosed floating-point notation conversion anomaly handling facility can be applied to an pair of floating-point notation systems that are not totally coincident in value coverage.
