![]() To review, open the file in an editor that reveals hidden Unicode characters. ![]() The user input and conversion factor might not be in the correct format, so it checks for the original value to be a number, as well as that the conversion can be converted to a fraction assuming that /number means 1/number, or there are a numerator and a denominator in the format number/number. JavaScript: Decimal To Fraction Raw decimalToFraction.js This file contains bidirectional Unicode text that may be interpreted or compiled differently than what appears below. However, most of the features Fraction. When working with currencies, decimals only need to be. Of course, there already exists a library that implements fractions beautifully in JavaScript - Fraction.js, which would be very useful for general purposes. The objects are available for all supported scripting languages. When converting a Fraction to a number, precision may be lost. The abs() function will try to convert the number parameter to a numeric value before calculating the absolute value. Floating-point numbers have a fractional part that can be as small as 5x10-324. ![]() In other words, I just wanted the fractional part of the passed number. One thing I recently wanted to do was effectively the opposite of parseInt(). Also doing math with these numbers is even more iffy. I developed a function to convert a value using a factor that may be passed as a fraction of integers or decimals. currency.js was built to work around common floating point issues in javascript with a flexible api. Fractions can be converted to numbers and vice versa using the functions number and fraction. One thing that is common knowledge about JavaScript and other languages is that floating point numbers are not always stored the way you think.
