Member Typedef Documentation

predicate_t

typedef uint32_t predicate_t

Dummy datatype. Must be present for building but not used since by default there is no vector architecture assumed

storage_type

typedef double storage_type

Storage datatype

temp_accumulator

typedef bool temp_accumulator

Dummy datatype. Must be present for building but not used since by default there is no vector architecture assumed

type

typedef double type

Scalar datatype

vector

typedef bool vector

Dummy datatype. Must be present for building but not used since by default there is no vector architecture assumed

Field Documentation

has_vector

constexpr bool has_vector = false

staticconstexpr

By default : no vector architecture assumed
