IEEE-754标准,英文版Abstract: This standard specifies interchange and arithmetic formats and methods for binary and decimal floating-point arithmetic in computer programming environments. This standard specifies exception conditions and their default hand
IEEE 754 为便于软件的移植,浮点数的表示格式应该有统一标准(定义)。1985年IEEE(Institute of Electrical and Electronics Engineers)提出了IEEE754标准。该标准规定基数为2,阶码E用移码表示,尾数M用原码表示,根据原码的规格化方法,最高数字位总是1,该标准将这个1缺省存储,使得尾数表示范围比实际存储的多一位
此标准规定了计算机编程环境下,二进制和十进制浮点数及其运算的格式和方法,异常的出现条件以及它们的默认句柄。此规范中的浮点数系统可以通过软件、硬件,或者软硬件相结合的形式来实现。对于标准中规定的运算,输出的结果、异常有输入值、操作序列和结果的数据格式所唯一确定,完全在用户的掌控之下。 This standard specifies interchange and arithmetic formats and methods for binary and decimal floating-poin
IEEE Standard 754 floating point is the most common representation today for real numbers on computers, including Intel-based PC's, Macintoshes, and most Unix platforms. This article gives a brief overview of IEEE floating point and its representati
