个人简介
In 1977 Kahan became active in the fledgling IEEE effort initiated by Robert Stewart to define a standard for computer arithmetic. Variations in floating-point arithmetics implemented on different kinds of computers often caused programs written in a standard language such as FORTRAN to give very different results when recompiled and run on another computer. The sudden proliferation of microprocessors and workstation systems threatened to worsen diversity and render uneconomical the development, testing and wide distribution of engineering and even some business software.
Most people expected the IEEE committee to endorse the existing approach of some particular manufacturer, such as DEC or IBM. Instead, Kahan persuaded the committee to endorse an entirely new design modeled on his then-secret work for Intel. The committee's doubts about efficient implementation were eventually overcome in what Kahan termed "late-night educational sessions." By the time the standard was officially adopted as IEEE 754 in 1985, it had already been implemented widely based on drafts published from 1979 onward with the help of his then graduate student Jerome Coonen. Kahan won the ACM’s Turing Award in 1989 for his work in creating that IEEE 754 standard, and he has often been called “The Father of Floating Point”.
