BitConverter::GetBytes Method (Double)
.NET Framework (current version)
Returns the specified double-precision floating point value as an array of bytes.
Assembly: mscorlib (in mscorlib.dll)
Parameters
- value
-
Type:
System::Double
The number to convert.
The order of bytes in the array returned by the GetBytes method depends on whether the computer architecture is little-endian or big-endian.
The following code example converts the bit patterns of Double values to Byte arrays with the GetBytes method.
// Example of the BitConverter::GetBytes( double ) method. using namespace System; // Convert a double argument to a byte array and display it. void GetBytesDouble( double argument ) { array<Byte>^byteArray = BitConverter::GetBytes( argument ); Console::WriteLine( "{0,25:E16}{1,30}", argument, BitConverter::ToString( byteArray ) ); } int main() { Console::WriteLine( "This example of the BitConverter::GetBytes( double ) " "\nmethod generates the following output.\n" ); Console::WriteLine( "{0,25:E16}{1,30}", "double", "byte array" ); Console::WriteLine( "{0,25:E16}{1,30}", "------", "----------" ); // Convert double values and display the results. GetBytesDouble( 0.0 ); GetBytesDouble( 1.0 ); GetBytesDouble( 255.0 ); GetBytesDouble( 4294967295.0 ); GetBytesDouble( 0.00390625 ); GetBytesDouble( 0.00000000023283064365386962890625 ); GetBytesDouble( 1.23456789012345E-300 ); GetBytesDouble( 1.2345678901234565 ); GetBytesDouble( 1.2345678901234567 ); GetBytesDouble( 1.2345678901234569 ); GetBytesDouble( 1.23456789012345678E+300 ); GetBytesDouble( Double::MinValue ); GetBytesDouble( Double::MaxValue ); GetBytesDouble( Double::Epsilon ); GetBytesDouble( Double::NaN ); GetBytesDouble( Double::NegativeInfinity ); GetBytesDouble( Double::PositiveInfinity ); } /* This example of the BitConverter::GetBytes( double ) method generates the following output. double byte array ------ ---------- 0.0000000000000000E+000 00-00-00-00-00-00-00-00 1.0000000000000000E+000 00-00-00-00-00-00-F0-3F 2.5500000000000000E+002 00-00-00-00-00-E0-6F-40 4.2949672950000000E+009 00-00-E0-FF-FF-FF-EF-41 3.9062500000000000E-003 00-00-00-00-00-00-70-3F 2.3283064365386963E-010 00-00-00-00-00-00-F0-3D 1.2345678901234500E-300 DF-88-1E-1C-FE-74-AA-01 1.2345678901234565E+000 FA-59-8C-42-CA-C0-F3-3F 1.2345678901234567E+000 FB-59-8C-42-CA-C0-F3-3F 1.2345678901234569E+000 FC-59-8C-42-CA-C0-F3-3F 1.2345678901234569E+300 52-D3-BB-BC-E8-7E-3D-7E -1.7976931348623157E+308 FF-FF-FF-FF-FF-FF-EF-FF 1.7976931348623157E+308 FF-FF-FF-FF-FF-FF-EF-7F 4.9406564584124654E-324 01-00-00-00-00-00-00-00 NaN 00-00-00-00-00-00-F8-FF -Infinity 00-00-00-00-00-00-F0-FF Infinity 00-00-00-00-00-00-F0-7F */
