Floating Point 1.1. Formats Floating point encodings and functionality are defined in the IEEE 754 Standard [2] last revised in 2008. Goldberg [5] gives a good introduction to floating point and many of the issues that arise. The standard mandates binary floating point data be encoded on ...
尾数实际上是有效数字的非正式说法。 在IEEE 标准中,浮点数是将特定长度的连续字节的所有二进制位分割为特定宽度的符号域,指数域和尾数域三个域,其中保存的值分别用于表示给定二进制浮点数中的符号,指数和尾数。这样,通过尾数和可以调节的指数(所以称为"浮点")就可以表达给定的数值了。具体的格式参见下面的图例: ...

In order to ensure consistent computations across platforms and to exchange floating point data, IEEE 754 defines basic and interchange formats. The 32 and 64 bit basic binary floating point formats correspond to the C data typesfloatanddouble. Their corresponding representations have the following bit...
This article specifies how single precision (32 bit) and double precision (64 bit) floating point numbers are to be represented as per IEEE Standard 754.Floating point Representation:Floating-point representation represents real numbers in scientific notation. Scientific notation represents numbers as a...

Both functions assume that the IBM data have been converted to NumPy integer format in such a way that the most significant bits of the floating-point number become the most significant bits of the integer values. So when decoding byte data representing IBM hexadecimal floating-point numbers, it...
