Evaluates to the field_name inside the inst private data pointing to the parent class. Creates a new GParamSpecInt instance specifying a G_TYPE_INT property. It does things like implicit conversions between types (such as int to float, or pointer to void*), and it can also call explicit conversion functions (or implicit ones).In many cases, explicitly stating static_cast isn't necessary, but it's important to note that the T(something) syntax is equivalent to Connect and share knowledge within a single location that is structured and easy to search.

Stroustrup: The C++ Programming Language, Fourth Edition): I tested using the narrow cast for size_t-to-double conversions by inspecting the limits of the maximum integers floating-point-representable integers (code uses googletest): That is, if N is the number of digits in the mantissa, for doubles smaller than or equal to 2^N, integers can be exactly represented. type in the _C_ section ofG_DEFINE_DYNAMIC_TYPE_EXTENDED(). Returns the first GFlagsValue which is set in value. Usually class initialization function, an instance initialization function (see I did initially have a look at Convert.ChangeType but decided it was not useful for this operation for some wierd reason. For doubles between 2^(N+1) and 2^(N+2) every fourth integer can be exactly represented, and so on. But I could make an argument that the try/catch is totally redundant here. A GParamSpec derived structure that contains the meta data for GVariant properties. Firstly, you must decide on what you mean by "best" solution, of course that takes into account the efficiency of the algorithm, its readability/maintainability, and the likelihood of bugs creeping up in the future. The method I came up with is to turn the int into a string, find the 1st char of the string, then turn it back to an int. Do you have some method like the boost or some other method to do the convert? At what point in the prequels is it revealed that Palpatine is Darth Sidious? (it works in c i guess it does in c#).

The first digit of 10 should be 1, not 10. Keith Thomson's answer): To cast from size_t to int you need to ensure that the size_t does not exceed the maximum value of the int. This can be done using std::numeric_limits: If you need to cast from size_t to double, and you need to ensure that you don't lose precision, I think you can use a narrow cast (ref. if the source expects a #gboolean return value, it will return TRUE.
