Given a decimal number with 2 decimal places representing the total cost of an item and another decimal number representing the quantify, calculate the unit price with 2 decimal places rounded half up?  Problem was derived from question posted on IBM Mainframe Assembler-List by Ludmila Koganer.

I think the most straight forward solution using the least instructions may be done using the new Decimal Floating Point (DFP) instructions.  However the most efficient may be done using basic packed decimal instructions and no floating point instructions.  For more information on ZMFACC problems and solutions visit the web site here:
