How to Handle Decimal Floating-point in a Binary Floating-point Computer World

Most computers today contain binary floating-point hardware. Though this satisfies some calculation requirements, binary floating-point logic is not useful for financial, commercial and user-centric applications, or for Web services. The decimal data that these applications use cannot be represented exactly by using binary floating-point, which, many times, cannot precisely represent decimal fractions. This presentation introduces different DFP standards, and available software and hardware which applications can take advantage of their DFP operations.
