Methods

ConvertToFloat(Half[])

Converts an array of half precision values into full precision values.

public static float[] ConvertToFloat(Half[] values)

Parameters

values Half[]

The values to be converted.

Returns

float[]

An array of converted values.

ConvertToHalf(float[])

Converts an array of full precision values into half precision values.

public static Half[] ConvertToHalf(float[] values)

Parameters

values float[]

The values to be converted.

Returns

Half[]

An array of converted values.

Equals(Half)

Returns a value that indicates whether the current instance is equal to the specified object.

public readonly bool Equals(Half other)

Parameters

other Half

Object to make the comparison with.

Returns

bool

true if the current instance is equal to the specified object; false otherwise.

Equals(ref Half, ref Half)

Determines whether the specified object instances are considered equal.

public static bool Equals(ref Half value1, ref Half value2)

Parameters

value1 Half

value2 Half

Returns

bool

true if value1 is the same instance as value2 or if both are null references or if value1.Equals(value2) returns true; otherwise, false.

Equals(object?)

Returns a value that indicates whether the current instance is equal to a specified object.

public override readonly bool Equals(object? obj)

Parameters

obj object

Object to make the comparison with.

Returns

bool

true if the current instance is equal to the specified object; false otherwise.

GetHashCode()

Returns the hash code for this instance.

public override readonly int GetHashCode()

Returns

int

A 32-bit signed integer hash code.

ToString()

Converts the value of the object to its equivalent string representation.

public override readonly string ToString()

Returns

string

The string representation of the value of this instance.

Operators

operator ==(Half, Half)

Tests for equality between two objects.

public static bool operator ==(Half left, Half right)

Parameters

left Half

The first value to compare.

right Half

The second value to compare.

Returns

bool

true if left has the same value as right; otherwise, false.

implicit operator float(Half)

Performs an implicit conversion from SharpDX.Half to float.

public static implicit operator float(Half value)

Parameters

value Half

The value to be converted.

Returns

float

The converted value.

implicit operator Half(float)

Performs an explicit conversion from float to SharpDX.Half.

public static implicit operator Half(float value)

Parameters

value float

The value to be converted.

Returns

Half

The converted value.

operator !=(Half, Half)

Tests for inequality between two objects.

public static bool operator !=(Half left, Half right)

Parameters

left Half

The first value to compare.

right Half

The second value to compare.

Returns

bool

true if left has a different value than right; otherwise, false.
