The floating point result comprises a p-bit mantissa. An unrounded proposed mantissa result is determined using the Newton-Raphson technique, wherein a p-bit rounded proposed mantissa result, t, corresponds to a rounding of the unrounded proposed mantissa result in accordance with the rounding mode, with k leading zeroes. If an increment to the (m−k)th bit of the unrounded result would affect the p-bit rounded result then the input(s) and bits of the unrounded result are used to determine a check parameter which is indicative of a relationship between an exact result and the unrounded result if the (m−k)th bit were incremented. The p-bit mantissa of the floating point result, is determined in dependence upon the check parameter, to be either t or t+1."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Check procedure for floating point operations","description":"Method and computer system for implementing an operation on ≧1 floating point input, in accordance with a rounding mode, e.g. using a Newton-Raphson technique.
