Logic (boolean) operator; returns 1 if both conditionA

conditionA and conditionB can be real numbers,

If both conditions are lists, they must have the same
number of elements. If one condition is a list and the
other a non-list, the non-list is compared with each
element of the list, and a list is returned.
Test operations are frequently used in programs.
