float在1e+8的时候已经不行了吧，输出一下显示a=b了
程序代码：#include<iostream> using namespace std; int ch(float x) { int count = 0; while (x > 1.0 && fabs(x - 1.0) > 1e-6) { x /= 10; count++; } return count; } int main(void) { float a = 1.23e+8; float b = a+1; if (a < b && fabs(a - b) > 1e-6) cout << "a<b" << endl; else if (a > b&& fabs(a - b) > 1e-6) cout << "a>b" << endl; else cout << "a=b" << endl; cout <<"a位数="<< ch(a)<<endl; cout << "b位数="<<ch(b) << endl; cout << "b-a=" << b - a << endl; } |
