can anybody tell me why modf(pow(216,1/double(3)),&s)=1.0?

I mean that its value should be 0 instead of 1
Floating point error

I guess you can solve this by adding a small value
like printf("%lf",modf(pow(216,1/double(3))+1e-15,&s));
Cause is floating point error. The computer is interpreting the value as
5.999999... instead of 6
