Handling overflow when casting doubles to integers in C

Question

Today, I noticed that when I cast a double that is greater than the maximum possible integer to an integer, I get -2147483648. Similarly, when I cast a double that is less

Answer 1

Another option is to use boost::numeric_cast which allows for arbitrary conversion between numerical types. It detects loss of range when a numeric type is converted, and throws an exception if the range cannot be preserved.

The website referenced above also provides a small example which should give a quick overview on how this template can be used.

Of course, this isn't plain C anymore ;-)
