simdpp::avg_trunc
template<unsigned N, class E1, class E2>
Ret<N, _DETAIL_> avg_trunc( Vec1<N,E1> a, Vec2<N,E2> b ); |
||
Computes truncated average of values in two integer values. 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 |
The return type is a vector expression.
Scalar arguments[edit]
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. Each element of the expanded vector contains bitwise representation of the source value, with the highest bits discarded if the source data is too large.
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[edit]
a, b | - | integer vectors |
Return value[edit]
A vector expression evaluating to (a + b) / 2
.
Equivalent operation[edit]
r0 = (a0 + b0) / 2 ... rN = (aN + bN) / 2
