* The inexactness for fractional periods arises because interest is calculated linearly during a period. For example, $100 at 10% is worth $105 in half a year, yet <tt>'''DURATION(10%; 100; 105)'''</tt> does <u>not</u> return exactly 0.5. This may be of more theoretical than practical importance. | * The inexactness for fractional periods arises because interest is calculated linearly during a period.
