BitConverter::GetBytes Method (Single)
Visual Studio 2010
Returns the specified single-precision floating point value as an array of bytes.
Assembly: mscorlib (in mscorlib.dll)
Parameters
- value
- Type: System::Single
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 Single values to Byte arrays with the GetBytes method.
// Example of the BitConverter::GetBytes( float ) method. using namespace System; // Convert a float argument to a byte array and display it. void GetBytesSingle( float argument ) { array<Byte>^byteArray = BitConverter::GetBytes( argument ); Console::WriteLine( "{0,16:E7}{1,20}", argument, BitConverter::ToString( byteArray ) ); } int main() { Console::WriteLine( "This example of the BitConverter::GetBytes( float ) " "\nmethod generates the following output.\n" ); Console::WriteLine( "{0,16:E7}{1,20}", "float", "byte array" ); Console::WriteLine( "{0,16:E7}{1,20}", "-----", "----------" ); // Convert float values and display the results. GetBytesSingle( 0.0F ); GetBytesSingle( 1.0F ); GetBytesSingle( 15.0F ); GetBytesSingle( 65535.0F ); GetBytesSingle( 0.00390625F ); GetBytesSingle( 0.00000000023283064365386962890625F ); GetBytesSingle( 1.2345E-35F ); GetBytesSingle( 1.2345671F ); GetBytesSingle( 1.2345673F ); GetBytesSingle( 1.2345677F ); GetBytesSingle( 1.23456789E+35F ); GetBytesSingle( Single::MinValue ); GetBytesSingle( Single::MaxValue ); GetBytesSingle( Single::Epsilon ); GetBytesSingle( Single::NaN ); GetBytesSingle( Single::NegativeInfinity ); GetBytesSingle( Single::PositiveInfinity ); } /* This example of the BitConverter::GetBytes( float ) method generates the following output. float byte array ----- ---------- 0.0000000E+000 00-00-00-00 1.0000000E+000 00-00-80-3F 1.5000000E+001 00-00-70-41 6.5535000E+004 00-FF-7F-47 3.9062500E-003 00-00-80-3B 2.3283064E-010 00-00-80-2F 1.2345000E-035 49-46-83-05 1.2345671E+000 4B-06-9E-3F 1.2345673E+000 4D-06-9E-3F 1.2345676E+000 50-06-9E-3F 1.2345679E+035 1E-37-BE-79 -3.4028235E+038 FF-FF-7F-FF 3.4028235E+038 FF-FF-7F-7F 1.4012985E-045 01-00-00-00 NaN 00-00-C0-FF -Infinity 00-00-80-FF Infinity 00-00-80-7F */
