-
template<class B>
inline batch_type_t<B> xsimd::ceil(const simd_base<B> &x)¶ Computes the batch of smallest integer values not less than scalars in
x
.- Parameters
x – batch of floating point values.
- Returns
the batch of smallest integer values not less than
x
.
-
template<class B>
inline batch_type_t<B> xsimd::floor(const simd_base<B> &x)¶ Computes the batch of largest integer values not greater than scalars in
x
.- Parameters
x – batch of floating point values.
- Returns
the batch of largest integer values not greater than
x
