AVX编程：标量浮点运算详解

1. 温度转换示例（Ch05_01）

首先来看温度转换的结果，这里展示了 ConvertFtoC_avx() 和 ConvertCtoF_avx() 两个函数的转换结果，如下表所示：
| 函数 | i | 输入值 | 输出值 |
| — | — | — | — |
| ConvertFtoC_avx() | 0 | f: -459.6700 | c: -273.1500 |
| ConvertFtoC_avx() | 1 | f: -40.0000 | c: -40.0000 |
| ConvertFtoC_avx() | 2 | f: 0.0000 | c: -17.7778 |
| ConvertFtoC_avx() | 3 | f: 32.0000 | c: 0.0000 |
| ConvertFtoC_avx() | 4 | f: 72.0000 | c: 22.2222 |
| ConvertFtoC_avx() | 5 | f: 98.6000 | c: 37.0000 |
| ConvertFtoC_avx() | 6 | f: 212.0000 | c: 100.0000 |
| ConvertCtoF_avx() | 0 | c: -273.1500 | f: -459.6700 |
| ConvertCtoF_avx() | 1 | c: -40.0000 | f: -40.0000 |
| ConvertCtoF_avx() | 2 | c: -17.7778 | f: 0.0000 | <
