Modular programming is a software design technique that emphasizes separating the functionality of a program into independent, interchangeable modules, such that each contains everything necessary to execute only one aspect of the desired functionality.
So if the value of the price index for the current year is equal to 165, and last year's value was 150, the rate would be calculated as: Inflation rate = (165 - 150) X100= 10.
It lists all the Consumer Price Index (CPI-U) numbers from January 2000 to the Present. The Consumer Price Index (CPI-U) is compiled by the Bureau of Labor Statistics and is based upon a 1982 Base of 100. Therefore, a Consumer Price Index of 158 would indicate 58% inflation since 1982. The commonly quoted inflation rate of say 3% is actually the change in the Consumer Price Index from a year earlier. By looking at the change in the index we can see that what cost an average of 9.9 cents in 1913 would cost about $1.82 in 2003 and $2.30 in August of 2012.
