设计了一个双精度浮点乘法器。该器件采用改进的BOO TH 算法产生部分积, 用阵列和 树的混合结构实现对部分积的相加, 同时, 还采用了快速的四舍五入算法, 以提高乘法器的性能。把 设计的乘法器分为4 级流水线, 用FPGA 进行了仿真验证, 结果正确 并对FPGA 实现的时序结果 进行了分析。-Designed a double-precision floating-point multiplier. The device uses an improved algorithm fo

在DELPHI中如何出神入化地用四舍五入： Delphi中的round()很多人认为不好用，下面的方法会较好去处理-Rounded down how superb in DELPHI: Delphi in the round () Many people think that does not work well, the following method would be better to deal with

请编写一个函数fun,函数的功能是使实数型数保留2位小数，并对第三位进行四舍五入（规定实行数为正数）。-Please write a function fun, function function is to make real type number 2 decimal places, and rounding third (providing for the number is a positive number).
