copied!<p>Well, seems I finally had to do it myself. I just had to create a program simulating the natural way I would solve it myself. I just submitted the code to codeproject as writing out the whole code here won't be suitable. You can download the project from here <a href="http://www.codeproject.com/KB/cs/Fraction_Conversion/Frac.zip" rel="nofollow">Fraction_Conversion</a>, or look at <a href="http://www.codeproject.com/Articles/165320/Easy-Way-of-Converting-a-Decimal-to-a-Fraction" rel="nofollow">the codeproject page here</a>.</p> <p>Here's how it works:</p> <ol> <li>Find out whether given decimal is negative</li> <li>Convert decimal to absolute value</li> <li>Get integer part of given decimal</li> <li>Get the decimal part</li> <li>Check whether decimal is recurring. If decimal is recurring, we then return the exact recurring decimal</li> <li>If decimal is not recurring, start reduction by changing numerator to 10^no. of decimal, else we subtract 1 from numerator</li> <li>Then reduce fraction</li> </ol> <p>Code Preview:</p> <pre><code> private static string dec2frac(double dbl) { char neg = ' '; double dblDecimal = dbl; if (dblDecimal == (int) dblDecimal) return dblDecimal.ToString(); //return no if it's not a decimal if (dblDecimal < 0) { dblDecimal = Math.Abs(dblDecimal); neg = '-'; } var whole = (int) Math.Truncate(dblDecimal); string decpart = dblDecimal.ToString().Replace(Math.Truncate(dblDecimal) + ".", ""); double rN = Convert.ToDouble(decpart); double rD = Math.Pow(10, decpart.Length); string rd = recur(decpart); int rel = Convert.ToInt32(rd); if (rel != 0) { rN = rel; rD = (int) Math.Pow(10, rd.Length) - 1; } //just a few prime factors for testing purposes var primes = new[] {41, 43, 37, 31, 29, 23, 19, 17, 13, 11, 7, 5, 3, 2}; foreach (int i in primes) reduceNo(i, ref rD, ref rN); rN = rN + (whole*rD); return string.Format("{0}{1}/{2}", neg, rN, rD); } </code></pre> <p>Thanks @ Darius for given me an idea of how to solve the recurring decimals :)</p>
