Hi,

I have been trying to figure this out and I know it must be something simple but I cant get it. Why does the following code give an answer of 1.

double a=8;
cout<<pow(a,1/3);

I would think it should be 2.
Thanks

1/3 is integer division which results in 0. Try 1.0/3.0 to get float division.

Just to clarify (words mean things)

What you've got is the result of integer division.

Truncation is what happens when you assign a floating point value that has a fractional part to an integer variable, or typecast the floating point to an integer type.
