Class special_scalar_constants¶

`class` special_scalar_constants<T> simd ¶

template <typename T>
struct special_scalar_constants { … }

Provides special bit-pattern constants for a scalar type.

The default implementation is intended for integer types. Floating-point types use specializations that provide their corresponding IEEE 754 masks.

Template parameters
T	Scalar type for which the constants are provided.

`function` highbitmask() ¶

constexpr static T highbitmask() { … }

Returns a value with only the most significant bit set.

Fully qualified name: kfr::special_scalar_constants<T>::highbitmask()

Declared at simd/types.hpp:61

`function` allones() ¶

constexpr static T allones() { … }

Returns a value with all bits set.

Fully qualified name: kfr::special_scalar_constants<T>::allones()

Declared at simd/types.hpp:63

`function` allzeros() ¶

constexpr static T allzeros() { … }

Returns a value with all bits cleared.

Fully qualified name: kfr::special_scalar_constants<T>::allzeros()

Declared at simd/types.hpp:65

`function` invhighbitmask() ¶

constexpr static T invhighbitmask() { … }

Returns a value with every bit except the most significant bit set.

Fully qualified name: kfr::special_scalar_constants<T>::invhighbitmask()

Declared at simd/types.hpp:67

Fully qualified name: kfr::special_scalar_constants<T>

`function` highbitmask() ¶

constexpr static float highbitmask() { … }

Returns negative zero, whose sign bit is set.

Fully qualified name: kfr::special_scalar_constants<float>::highbitmask()

Declared at simd/types.hpp:80

`function` allones() ¶

constexpr static float allones() noexcept { … }

Returns a floating-point value with all bits set.

`function` allzeros() ¶

constexpr static float allzeros() { … }

Returns positive zero, whose bits are all cleared.

Fully qualified name: kfr::special_scalar_constants<float>::allzeros()

Declared at simd/types.hpp:84

`function` invhighbitmask() ¶

constexpr static float invhighbitmask() { … }

Returns a floating-point value with every bit except the sign bit set.

Fully qualified name: kfr::special_scalar_constants<float>::invhighbitmask()
