iOS Metal: casting half4 variable to float4 type

I am using a sampler to sample from texture:

constexpr sampler cubeSampler(filter::linear, mip_filter::none);
half4 res = cubeTexture.sample(cubeSampler, texVec);

The result is of type half4 but i need to cast it to float4 in order to perform math operations. How can i perform this cast?

static_cast works, or you can use the more terse converting constructor:

float4 res_float4 = float4(res);

constexpr sampler cubeSampler(filter::linear, mip_filter::none);
half4 res = cubeTexture.sample(cubeSampler, texVec);

// cast to float4:
float4 res_float4 =  static_cast<float4>(res);
