Nettet26. jan. 2016 · In June 1994, about a year after Intel launched the Pentium microprocessor with much fanfare and a massive advertising campaign, some Internet newsgroups started discussing a flaw in the Pentium’s floating point unit. This error caused occasional mathematical errors in the chip’s advanced number-crunching component. Intel knew … NettetControlling Floating-Point Rounding Operations ( -fp-model= ) Include the -fp-model= option in your dpcpp command to direct the Intel® oneAPI DPC++/C++ Compiler to control the semantics of floating-point operations. You can also use the Floating Point Pragmas to influence the floating-point operations. Example

Nettet•The finite precision of floating-point operations leads to an inherent uncertainty in the results of a floating-point computation – Results may vary within this uncertainty •Nevertheless, may need reproducibility beyond this uncertainty – For reasons of Quality Assurance, e.g. when porting, optimizing, etc NettetSet round positive infinity. Load ULP. Nudge inward. Nudge outward. Get sign bit (slightly different than "get sign"). Xor sign bits, output to integer or flag (or maybe just "branch if sign bits (don't) differ"). Copy sign bit to another floating-point value. Nudge positive. Nudge negative. +-0.0 -> +-epsilon (smallest-magnitude nonzero float). NettetDSP Builder Supported Floating-Point Data Types 11.3.
