Type conversionΒΆ

Cast:

batch_cast()

static_cast on batch types

bitwise_cast()

reinterpret_cast on batch types

batch_bool_cast()

static_cast on batch predicate types

Conversion:

to_float()

per slot conversion to floating point

to_int()

per slot conversion to integer
template <class T_out, class T_in, class A>
XSIMD_INLINE batch_bool<T_out, A> xsimd::batch_bool_cast(batch_bool< T_in, A > const & x)

Perform a static_cast from T_in to T_out on .

Return

x cast to T_out

Parameters

template <class T_out, class T_in, class A>
XSIMD_INLINE batch<T_out, A> xsimd::batch_cast(batch< T_in, A > const & x)

Perform a static_cast from T_in to T_out on .

Return

x cast to T_out

Parameters

  • x: batch of T_in

template <class T_out, class T_in, class A>
XSIMD_INLINE batch<T_out, A> xsimd::bitwise_cast(batch< T_in, A > const & x)

Perform a reinterpret_cast from T_in to T_out on x.

Return

x reinterpreted as T_out

Parameters

  • x: batch of T_in

template <class T, class A>
XSIMD_INLINE batch<as_float_t<T>, A> xsimd::to_float(batch< T, A > const & i)

Perform a conversion from i to a value of an floating point type of the same size as T.

This is equivalent to batch_cast<as_float_t<T>>(i)

Return

i converted to a value of an floating point type of the same size as T

Parameters

  • i: batch of integers.

template <class T, class A>
XSIMD_INLINE batch<as_integer_t<T>, A> xsimd::to_int(batch< T, A > const & x)

Perform a conversion from x to a value of an integer type of the same size as T This is equivalent to batch_cast<as_integer_t<T>>(x)

Return

x converted to a value of an integer type of the same size as T

Parameters

  • x: batch.

template <class T, class A, typename std::enable_if< std::is_integral< T >::value, int >::type = 3>
XSIMD_INLINE batch< T, A > xsimd::bitwise_cast(batch_bool< T, A > const & self)

Cast a batch_bool of T into a batch of the same type using the following rule: if an element of self is true, it maps to -1 in the returned integral batch, otherwise it maps to 0.

Return

self cast to a batch of T
