System::BitConverter class

BitConverter class

Contains methods that perform conversions of sequence of bytes to a value type and vice-versa. This is a static type with no instance services. You should never create instances of it by any means.

Fields

FieldDescription
static IsLittleEndianIndicates the endianness of the current architecture. true if the architecture is little endian, false otherwise.

Remarks

#include <system/bit_converter.h>
#include <system/smart_ptr.h>

using namespace System;

template <typename T>
void Print(T arg)
{
  std::cout << arg << ' ';

  for (const auto byte: BitConverter::GetBytes(arg))
  {
    std::cout << std::hex << static_cast<int>(byte);
  }

  std::cout << std::endl;
}

int main()
{
  // Create values to print.
  int anInt = 1234567890;
  double aDouble = 0.123456789;

  // Print value and its bytes.
  Print(anInt);
  Print(aDouble);

  return 0;
}
/*
This code example produces the following output:
1234567890 d229649
