PHP: Count a stdClass object
...(unless it's a custom object that implements the Countable interface). Try casting the object, like below, as an array and seeing if that helps.
$total = count((array)$obj);
Simply casting an object as an array won't always work but being a simple stdClass object it should get the job done here.

How do you determine the size of a file in C?
...
You could probably change the return type to ssize_t and cast the size from an off_t without any trouble. It would seem to make more sense to use a ssize_t :-) (Not to be confused with size_t which is unsigned and cannot be used to indicate error.)

Python division
... Python is giving you an integer back:
>>> 10 / 90
0
If if you cast this to a float afterwards the rounding will have already been done, in other words, 0 integer will always become 0 float.
If you use floats on either side of the division then Python will give you the answer you expect...

Why does Decimal.Divide(int, int) work, but not (int / int)?
...mals.
You can enforce non-integer division on int arguments by explicitly casting at least one of the arguments to a floating-point type, e.g.:
int a = 42;
int b = 23;
double result = (double)a / b;
