Examples

The following code shows how to use xtd::integer concept

#include <xtd/xtd>
 
auto print_is_integer(auto value) noexcept {
  println("{} ({}) {} integer", value, type_of(value), integer<decltype(value)> ? "is" : "is not");
}
 
auto main() -> int {
  print_is_integer(42_s8);
  print_is_integer(42_s16);
  print_is_integer(42_s32);
  print_is_integer(42_s64);
  print_is_integer(42_u8);
  print_is_integer(42_u16);
  print_is_integer(42_u32);
  print_is_integer(42_u64);
  print_is_integer(42_z);
  print_is_integer(42.84f);
  print_is_integer(42.84);
  print_is_integer(42.84l);
  print_is_integer('a');
  print_is_integer(true);
  print_is_integer("string"_s);
  print_is_integer("string");
  print_is_integer(1_h + 12_min + 24_s + 48_ms);
  print_is_integer(day_of_week::wednesday);
}
 
// This code produces the following output :
//
// 42 (signed char) is integer
// 42 (short) is integer
// 42 (int) is integer
// 42 (long long) is integer
// 42 (unsigned char) is integer
// 42 (unsigned short) is integer
// 42 (unsigned int) is integer
// 42 (unsigned long long) is integer
// 42 (unsigned long) is integer
// 42.84 (float) is not integer
// 42.84 (double) is not integer
// 42.84 (long double) is not integer
// true (bool) is not integer
// string (xtd::basic_string<char, std::char_traits<char>, std::allocator<char>>) is not integer
// string (char const*) is not integer
// 01:12:24.0480000 (xtd::time_span) is not integer
// wednesday (xtd::day_of_week) is not integer
