vllt

Perform real-number vector comparison operations (<).

The function interface declaration is as follows:

Operations on numbers of the float type:

void (vsip_vllt_f)(const vsip_vview_f *a, const vsip_vview_f *b, const vsip_vview_bl *r);

Parameters

Parameter	Description	Value Range	Input/Output
a	Pointer to the source vector	The value cannot be NULL.	Input
b	Pointer to the source vector	The value cannot be NULL.	Input
r	Pointer to the destination vector	The value cannot be NULL.	Output

Abnormal Input

When a null pointer is input, the function directly returns a result.
