Nearest integer floating point operations¶
-
template<class T, class A>
inline batch<T, A> xsimd::ceil(batch<T, A> const &x) noexcept¶ 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 T, class A>
inline batch<T, A> xsimd::floor(batch<T, A> const &x) noexcept¶ 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
.
-
template<class T, class A>
inline batch<T, A> xsimd::trunc(batch<T, A> const &x) noexcept¶ Computes the batch of nearest integer values not greater in magnitude than scalars in
x
.- Parameters:
x – batch of floating point values.
- Returns:
the batch of nearest integer values not greater in magnitude than
x
.
-
template<class T, class A>
inline batch<T, A> xsimd::round(batch<T, A> const &x) noexcept¶ Computes the batch of nearest integer values to scalars in
x
(in floating point format), rounding halfway cases away from zero, regardless of the current rounding mode.- Parameters:
x – batch of flaoting point values.
- Returns:
the batch of nearest integer values.
