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

Returns maximum of two values in two integer vectors. The implementation behaves as if the following set of overloads is provided:

Ret	Vec1	Vec2
int8	int8	int8
uint8	uint8	uint8
int16	int16	int16
uint16	uint16	uint16
int32	int32	int32
uint32	uint32	uint32
int64	int64	int64	(since AVX2, NEONv2)
uint64	uint64	uint64	(since AVX2, NEONv2)

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

-

integer vectors

Return value

A vector expression evaluating to max(a, b).
