Making decimal numbers fractions

megabri

Does anyone know if BIRT has a way of making decimal numbers into fractions. An example would be if I had 56.75 I'd want to show 56 3/4. Thanks!

I haven't used it but it looks like there is a JS lib that you could include in your report to do this, maybe in a computed column? <a data-ipb='nomediaparse' href='https://github.com/ekg/fraction.js'>Take a look at it here</a>

I'll give that a try. I've never included a library into a report before. How do I do it?

You should be able to add it as a resource in the resources tab from the property editor then call it like normal. You could also point to it <a data-ipb='nomediaparse' href='http://www.eclipse.org/birt/phoenix/project/notable4.3.php#jump_6'>using head.js.</a>

I tried the library and tried using the following line in my fetch row["ststswitchthrmeasure"] = new Fraction(maximoDataSet.getDouble("ststswitchthrmeasure")); When it printed out it printed as [object Object]. Any ideas how to make it work? Thanks!

Try using this, I found it online over the weekend and it works well in a text item.<pre class="_prettyXprint _lang-"><script>function highestCommonFactor(a,b) { if (b==0) return a; return highestCommonFactor(b,a%b);}var decimal = "13.42";var decimalArray = decimal.split(".");var leftDecimalPart = decimalArray[0];var rightDecimalPart = decimalArray[1];var numerator = leftDecimalPart + rightDecimalPartvar denominator = Math.pow(10,rightDecimalPart.length);var factor = highestCommonFactor(numerator, denominator);denominator /= factor;numerator /= factor;document.getElementById("solution").innerText = numerator + "/" + denominator;</script><div id="solution"></div></pre>

Hi, I made a very basic report using computed columnsIt calculated the decimal part in fraction. Hope it helps
