Half Struct

The name Half is derived from half-precision floating-point number. It occupies only 16 Bits, which are split into 1 Sign bit, 5 Exponent bits and 10 Mantissa bits.

Remarks
Quote from ARB_half_float_pixel specification: Any representable 16-bit floating-point value is legal as input to a GL command that accepts 16-bit floating-point data. The result of providing a value that is not a floating-point number (such as infinity or NaN) to such a command is unspecified, but must not lead to GL interruption or termination. Providing a denormalized number or negative zero to GL must yield predictable results.
Constructors
| Half(Double, Boolean) |
The new Half instance will convert the parameter into 16-Bit Half precision floating point. |
| Half(Double) |
The new Half instance will convert the parameter into 16-Bit Half precision floating point. |
| Half(SerializationInfo, StreamingContext) |
Constructor used by ISerializable to deserialize the object. |
| Half(Single, Boolean) |
The new Half instance will convert the parameter into 16-Bit Half precision floating point. |
| Half(Single) |
The new Half instance will convert the parameter into 16-Bit Half precision floating point. |
Fields
| Epsilon |
Smallest positive e for which half (1.0 + e) != half (1.0) |
| MaxValue |
Largest positive half |
| MinNormalizedValue |
Smallest positive normalized half |
| MinValue |
Smallest positive half |
| SizeInBytes |
The size in bytes for an instance of the Half struct. |
Properties
| IsNaN |
Returns true if the Half represents Not A Number (NaN) |
| IsNegativeInfinity |
Returns true if the Half represents negative infinity. |
| IsPositiveInfinity |
Returns true if the Half represents positive infinity. |
| IsZero |
Returns true if the Half is zero. |
Methods
| CompareTo(Half) |
Compares this instance to a specified half-precision floating-point number and returns an integer that indicates whether the value of this instance is less than, equal to, or greater than the value of the specified half-precision floating-point number. |
| Equals(Half) |
Returns a value indicating whether this instance is equal to a specified OpenTK.Half value. |
| FromBinaryStream(BinaryReader) |
Updates the Half by reading from a Stream. |
| FromBytes(Byte[], Int32) | |
| GetBytes(Half) |
Returns the Half as an array of bytes. |
| GetObjectData(SerializationInfo, StreamingContext) |
Used by ISerialize to serialize the object. |
| Parse(String, NumberStyles, IFormatProvider) | |
| Parse(String) | |
| ToBinaryStream(BinaryWriter) |
Writes the Half into a Stream. |
| ToSingle() |
Converts the 16-Bit half to 32-Bit floating point. |
| ToString() |
Converts this Half into a human-legible string representation. |
| ToString(String, IFormatProvider) |
Converts this Half into a human-legible string representation. |
| TryParse(String, Half) |
Converts the string representation of a number to a Half precision floating point equivalent. Returns success. |
| TryParse(String, NumberStyles, IFormatProvider, Half) |
Converts the string representation of a number to a Half precision floating point equivalent. Returns success. |
