Search arrays based on similar values

Hey folks,
I have two arrays: "A" (1X100) with non-ordered values ranging 1-14
                         "B" (2X14)  containing 14 decimal values.
I would like to create a new array (1X100) that contains only the  
decimal
values from array B by associating the integers from A and B.  In  
other
words, for each value of A find the same integer value of B, select  
the
associated decimal value of B.
