maybe a related question - how to you handle overflows - for example reading a too large value into a float? That's not supported, you'll need to provide a double or a 64 bit int. What do you mean by "not supported"? What happens when you read a value larger than INT_MAX to an int? Or a value exceeding FLOAT_MAX but still using a float? Will those be silently truncated, UB in case of int, wrapped to inf for float?
It won't compile. You can't read into an `int` implicitly.
Correction: I misremembered that part and didn't double check. You can read into an int implicitly, but you cannot read into a float, only double. So you can get an integer overflow if you're not careful.
