value
.

pub fn replace(self, index: usize, new_value: f32) -> Self
[src][−]
Returns a new vector where the value at index
is replaced by new_value
.

.
pub unsafe fn replace_unchecked(self, index: usize, new_value: f32) -> Self

pub fn min(self, x: Self) -> Self
[src][−]
Minimum of two vectors.
Returns a new vector containing the minimum value of each of the input vector lanes.
pub fn max(self, x: Self) -> Self

Returns a new vector containing the maximum value of each of the input vector lanes.
impl f32x8
[src][−]
pub fn sum(self) -> f32
[src][−]
Horizontal sum of the vector elements.
The intrinsic performs a tree-reduction of the vector elements. That is, for an 8 element vector:
((x0 + x1) + (x2 + x3)) + ((x4 + x5) + (x6 + x7))
If one of the vector element is NaN
the reduction returns
NaN
. The resulting NaN
is not required to be equal to any
of the NaN
s in the vector.
pub fn product(self) -> f32
[src][−]
Horizontal product of the vector elements.
The intrinsic performs a tree-reduction of the vector elements. That is, for an 8 element vector:
((x0 * x1) * (x2 * x3)) * ((x4 * x5) * (x6 * x7))
If one of the vector element is NaN
the reduction returns
NaN
. The resulting NaN
is not required to be equal to any
of the NaN
s in the vector.

pub fn mul_adde(self, y: Self, z: Self) -> Self

Fused multiply add estimate: ~= self * y + z

has at worst the same precision of a multiply followed by an add.
This might be more efficient on architectures that do not have an fma
instruction.
