浮点数基本运算 浮点数的基本运算主要有四则运算、符号处理、大小比较,以及浮点数分柝等。 包含头文件 "fn.hpp" #include "fn.hpp" 浮点数基本运算 浮点数的基本运算中有加、减、乘、除、取负、绝对值、相等比较等。 加减乘除 加、减、乘、除四个运算极为相似,都是需要两个参数,结果当然也是浮点数了。 例子: // 加 减 乘 除 btil::fn::plus::value // f1+f2 的结果 btil::fn::minus::value // f1-f2 的结果 btil::fn::multiplies::value // f1*f2 的结果 btil::fn::divides::value // f1/f2 的结果 plus::value::f_val // f1+f2 的结果的值 struct one { static const double f_val = 1.0 } // 两个浮点数 struct two { static const double f_val = 2.0 } minus::value::f_val == 0.5 取负 取负运算就是取一个浮点数的负数。-float basic operations of the basic operations are four major operations, symbols, sizes, and float-watchman"s rattle so. The first document contains "fn.hpp"# include "fn.hpp" float float basic operations of the basic operations are, plus or minus, riding, except from negative, in absolute terms, a comparison of the same.
