<para>Vector Absolute Compare Less Than or Equal takes the absolute value of each element in a vector, and compares it with the absolute value of the corresponding element of a second vector. If the first is less than or equal to the second, the corresponding element in the destination vector is set to all ones. Otherwise, it is set to all zeros.</para>
