You can use two for loops to check for duplicates. One for loop to keep track of the number you're searching for in the loop, the second one to check for duplicates and return the first for loop's position if found.
the standard approach is to sort the data, or a copy of it, and compare adjacent items for dupes.
floating point, you might want to check a tolerance rather than equality, depending on what you think is best. for example is 0.999999999999999 == to 1.000000000000000000001 ?
