## half2(half, half)

Constructs a half2 vector from two half values.

```csharp
public half2(half x, half y)
```

### Parameters

**** (\[half]\(/engine/6000.7/script-reference/unity/mathematics/half)): The constructed vector's x component will be set to this value.**** (\[half]\(/engine/6000.7/script-reference/unity/mathematics/half)): The constructed vector's y component will be set to this value.

## half2(half2)

Constructs a half2 vector from a half2 vector.

```csharp
public half2(half2 xy)
```

### Parameters

**** (\[half2]\(/engine/6000.7/script-reference/unity/mathematics/half2)): The constructed vector's xy components will be set to this value.

## half2(half)

Constructs a half2 vector from a single half value by assigning it to every component.

```csharp
public half2(half v)
```

### Parameters

**** (\[half]\(/engine/6000.7/script-reference/unity/mathematics/half)): half to convert to half2

## half2(float)

Constructs a half2 vector from a single float value by converting it to half and assigning it to every component.

```csharp
public half2(float v)
```

### Parameters

**** (\[float]\(https\://learn.microsoft.com/dotnet/api/system.single)): float to convert to half2

## half2(float2)

Constructs a half2 vector from a float2 vector by componentwise conversion.

```csharp
public half2(float2 v)
```

### Parameters

**** (\[float2]\(/engine/6000.7/script-reference/unity/mathematics/float2)): float2 to convert to half2

## half2(double)

Constructs a half2 vector from a single double value by converting it to half and assigning it to every component.

```csharp
public half2(double v)
```

### Parameters

**** (\[double]\(https\://learn.microsoft.com/dotnet/api/system.double)): double to convert to half2

## half2(double2)

Constructs a half2 vector from a double2 vector by componentwise conversion.

```csharp
public half2(double2 v)
```

### Parameters

**** (\[double2]\(/engine/6000.7/script-reference/unity/mathematics/double2)): double2 to convert to half2
