Thanks Charlton
Next question regards floor(). if pow(x, 1.0/3) returns a value that
can be represented as an integer (like 6.000000) executing floor
(6.000000) returns 5.000000. Why isn't it returning 6?
Because pow is likely not returning 6, but 5.999999... something. In
this case, you don't want to use floor, you want to round the value.
I looked at the various round functions but it doesn't look like you can tell
them to round down.
In this case, you don't want to round down, you want to round to the
nearest integer.
