Dear All Experts, Am new in TDL and progressing nicely and more or less I am expanding on projects-TDL made by others to suit my needs. Below is the Code which I have expanded but originally made in simple form by some other guy, whose ID i am not aware as i have downloaded it in a zip file. So due credit goes to the original developer. The code is for calculating Compound Interest (CI) on monthly, quarterly, half-yearly and yearly basis. Tally-TDL is rounding off the exponential to 2 decimals. Let me explain as below. Assume -Principal as 1,25,000/-, ROI as 8% and period as 5 years...... Exponential ROI for Monthly..... 1.489846 x 1,25,000/- = 1,86,231/- (Int-61233/-) Exponential ROI for Quarterly......1.485947 x 1,25,000/- = 1,85,741/- (Int-60741/-) Exponential ROI for Half-Yearly.....1.480244 x 1,25,000/- = 1,85,024/- (Int-60024/-) Exponential ROI for Yearly.....1.469328 x 1,25,000/- = 1,83,668/- (Int-58668/-) However, if you run the code...tally rounds of exponential ROI as 1.49, 1.49, 1.48 and 1.46 respectively And it gives the figure as 61,250/-, 61,250/-, 60,000/- and 58,750/- as Interest respectively. From the attached code, can the EXPERTS show me how to make Tally take the ROI upto 4 or 6 decimals, so that the actual figures of Compounded Interest is arrived at. here is the code attached.... Help will be greatly appreciated. Thanks in Advance.
