We review some of the basic properties of floating point calculations in Chapter 2. We also discuss the fused multiply-add operator, which was added to the IEEE 754 standard in 2008 [2] and is built into the hardware of NVIDIA GPUs. In Chapter 3 we work through an example of computing ...
1、其第31 bit为0,即s = 0 2、第30~23 bit依次为100 1001 1,读成十进制就是147,即e = 147。 3、第22~0 bit依次为110 0100 1000 1110 0110 1000,也就是二进制的纯小数0.110 0100 1000 1110 0110 1000,其十进制形式为(0.110 0100 1000 1110 0110 1000 * 2^23) / (2^23) = (0x49E48E68 ...
Portability note: the conversion functions provided in this module assume that numpy.float32 and numpy.float64 are based on the standard IEEE 754 binary32 and binary64 floating-point formats. This is true on the overwhelming majority of current platforms, but is not guaranteed by the relevant ...

注:单精度浮点型所谓的7.2位精度就是指的是有效位的范围,因为单精度浮点可以表达的最大指数为 2^24 - 1 = 16,777,215这个数就是有效位的最大表示数字了,超过这个数的就要进行取舍。 参考: IEEE 754 Floating-Point Format IEEE 754 FLOATING POINT REPRESENTATION...
IFloatingPointIeee754.cs 計算兩個值商的反正切值。 C# publicstaticabstractTSelfAtan2(TSelf y, TSelf x); 參數 y TSelf 點的Y 座標。 x TSelf 點的X 座標。 傳回 TSelf 除以的yx反正切值。 備註 這會以間隔[-π, +π]弧度計算arctan(y / x)。
