Example 33: Calculate Interest

Learn how to calculate interest on the given amount.

Problem

When interest compounds q times per year at an annual rate of r% for n years, the principal p compounds to an amount a as per the following formula:

a=p(1+rq100)nqa=p(1+ \frac{{r}}{q * 100})^{nq}

Write a program that takes the values of p, r, n, and q as input and calculates the corresponding amount a.

Example

Input (p, r, n, q) Output
1000, 7.5, 5, 1 1435.630
15000, 12, 4, 2 23907.711
10000, 3.5, 5, 2 11894.450
