class xsimd::simd_batch_bool¶ Base class for batch of boolean values.
The simd_batch_bool class is the base class for all classes representing a batch of boolean values. Batch of boolean values is meant for operations that may involve batches of integer or floating point values. Thus, the boolean values are stored as integer or floating point values, and each type of batch has its dedicated type of boolean batch.
