these are almost all the bignumber operations except big number mod(%) operation

thank you very much,Ghust_omega

int main(int argc, char* argv[])
{
double r,h,d1, A1, d2, A2,c ,temp,res;
int i,j,k;
while(scanf("%lf%lf%lf%lf%lf%lf",&r,&h,&d1,&A1,&d2,&A2)!=EOF)
{
if(d1>d2)
{
temp=d1;
d1=d2;
d2=temp;
}
c=2*d1*d1*(1-cos(fabs(A2-A1)*2*acos(-1)*r ...

anyone may help with this problem?

addition and subtraction are easy,but multiplication and division are quite difficult

what would the angle |A1-A2| be if the cone is unrolled ?

hi friends

I am green and trying to solve some big number problems. but i am always getting WA.Because my algorithm is not good.
can any body help me about this.I want some perfect big number algrithms such as multiplication ,division or mod operation
