Var quantitySplit = fractionString. (based on decimal values like 0.33, 0.11, 0.66) so I wrote a quick & dirty if/else to give me the lower fractions I was after: var fractionString = fraction.toString() In my most recent use-case, I wanted particular low fractions like 1/3, 1/9, 2/3 etc. ostensibly represents one third, but fractions.js would (correctly) return 33/100. It depends how low you want to go, though there are certain decimal values that notionally represent fractions, but can't be divided to the 'lowest' fraction that you might want. If the result contains an integer, it will return in the format int d/n so if you want just the fraction, you can split around the space. If the result is an integer, it will return the same integer. As per answer, it calculates the greatest common divisor of a non-integer and returns it as the lowest fraction it can make as a string: var myNum = 0.5 Ĭonsole.log(fraction.toString()) // Returns 1/2 If you're open to using a small third-party script, you could take a look at fraction.js. How would I be able to simplify these fractions? (I am decently new to code) Thanks :) So currently my calculator works but none of the fractions are simplified. Number4 = parseInt(document.getElementById("n4").value) Number3 = parseInt(document.getElementById("n3").value) Number2 = parseInt(document.getElementById("n2").value) Number1 = parseInt(document.getElementById("n1").value) So my current code for my multiplication part fo my calculator is this: function multiply() Selection = document.getElementById('operation').value They can also be useful in cases where your feature data has inconsistent types for example, you could use to-number to make sure that values like "1.5" (instead of 1.5) are treated as numeric values.The non script part of my calculator is this (With all the inputs): Īnd my option function is this: function option() Often, such tests and conversions are unnecessary, but they may be necessary in some expressions where the type of a certain sub-expression is ambiguous. Convert a decimal number to a fraction / rational number. Javascript - convert mixed fraction to decimal. var decimal 1.75 var decimalArray decimal.split('.') // 1.75 var leftDecimalPart. You can use type expressions to test and convert between different data types like strings, numbers, and boolean values. I wrote this simple script to convert a decimal to a fraction but it is not working. They can be used to differentiate features within the same layer and to create data visualizations. Data expressions allow a feature's properties or state to determine its appearance. Ī data expression is any expression that accesses feature data – that is, any expression that uses one of the data operators: get, has, id, geometry-type, properties, or feature-state. Each argument is either a literal value (a string, number, boolean, or null), or another expression array. Elements that follow (if any) are the arguments to the expression. The first element of an expression array is a string naming the expression operator, for example "*" or "case".
