 在运算的时候取对数就好了

#include <bits/stdc++.h>

using namespace std;

#define ll long long
#define eps 1e-6

int main()
{
    ll x,y;
    double xx;
    scanf("%lld %lld",&x,&y);
    xx = y*log10(x) - x*log10(y);
    if(fabs(xx-0) <= eps)
    {
        printf("=\n");
    }
    else
    {
        if(xx-0 < eps)
        {
            printf("<\n");
        }
        else
        {
            printf(">\n");
        }
    }

    return 0;
}
