Examples
Consider the following example that shows the use of MDURATION function:
| September 10, 2010 | ||
| September 10, 2014 | ||
| 6% | ||
| 9.0% | ||
| 2 | ||
| 1 |
=MDURATION(A1,A2,A3,A4,A5,A6) displays 3.8035273385670787 as a result. =MDURATION(DATE(2013,6,1),DATE(2013,12,31),"8%","9%",1,1) displays 0.9174311926605504 as a result.
