Web the numeric_limits class template provides a standardized way to query various properties of arithmetic types (e.g. In c++ we tend to define generic types based on other constraints other than inherits from this class. Web is it possible to limit a template class to certain types only.

Modified 9 years, 11 months ago. Web c++20 solution using constraints and concepts looks like this: For example, we can use the std::enable_if_t syntax. Suppose i have a limitedvalue class which holds a value, and is parameterized on int types 'min' and 'max'.
