template<unsigned N, class E1, class E2> Ret<N, _DETAIL_> add( Vec1<N,E1> a, Vec2<N,E2> b );

Performs addition of two floating-point values. The implementation behaves as if the following set of overloads is provided:

Ret	Vec1	Vec2
float32	float32	float32
float64	float64	float64

The return type is a vector expression.

Scalar arguments

Several additional overloads are provided to implement implicit conversions from scalar types. Values of the following types are accepted as the first or the second argument: int32_t, int64_t, uint32_t, uint64_t, float, double. Each element of the expanded vector is set to the source value, converting it using standard conversions if needed.

The return type is a vector expression. The vector type is the same as the vector argument except that masks are unmasked to respective non-mask vector types.

Parameters

a, b

-

floating-point vectors

Return value

A vector expression evaluating to a + b.

Equivalent operation

r0 = a0 + b0
...
rN = aN + bN
