| 摘要: |
| “二一十”转换是计算机中经常用到的，将二进制浮点数0.B1B2…Bn*2B 转换成十进制数 0.D1D2…Dm*10D 的关键是首先求出D。本文通过全面研制二进制浮点数的性质，推导出了一个关于精确求D的重要结论，并由此构造出一个实际应用时总误差最小的高效求D公式。 |

| Abstract: |
| The binary-to-decimal (BTD) conversion is often used in computer.It is the key problem to calculate D first for converting the binary floating point number (BFPN) O.B1B2…Bn*2B into the decimal 0.D1D2…Dm*10D. In this paper，we comprehensively studied the nature of BFPNand inferred an important conclusion for calculating D precisely. Based on the conclusion we constructed a high efficient formula which can not only calculate D but also keep the total error minimum in application. |
