Type conversion

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 > batch_bool_cast (batch_bool< T_in, A > const &x) noexcept

Perform a static_cast from T_in to T_out on .

Parameters:: x – batch_bool of T_in
Returns:: x cast to T_out

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

Perform a static_cast from T_in to T_out on .

Parameters:: x – batch of T_in
Returns:: x cast to T_out

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

Perform a reinterpret_cast from T_in to T_out on x.

Parameters:: x – batch of T_in
Returns:: x reinterpreted as T_out

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

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)

Parameters:: i – batch of integers.
Returns:: i converted to a value of an floating point type of the same size as T

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

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)

Parameters:: x – batch.
Returns:: x converted to a value of an integer type of the same size as T

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

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.

Parameters:: self – batch_bool of T
Returns:: self cast to a batch of T
