std::set precision 小数字问题描述 投票:0回答:1以下代码是使用VS2022编译的 #include <iostream> #include <iomanip> int main() { double d1 = 0.0006; double d2 = 0.00006; double d3 = 1.0006; double d4 = 1.00006; std::cout << "d1=" << std::setprecision(9) << d1 << "\n"; ...
#include <iostream> void print_div_result( unsigned int numerator, unsigned int denominator, unsigned int precision = 20 ) { std::cout << numerator << '/' << denominator << " == " ; if( denominator == 0 ) std::cout << ( numerator == 0 ? "NaN" : "+infinity" ) << '\n'...
