So best way to convert String to double is by using valueOf() method. So then how can i approximate into two decimal places, pass the values in decimal format AND include thousand separator?Īnother advantage of using valueOf() to convert String to double or Double is that valueOf() can cache frequently used double value and since Double is an immutable object you can safely reuse object. Yet the returned vary comes in exponential for it has too many digits eg 2678765E9 this returns a very huge number (double), my aim is to return a double with two decimal placesīut i've failled and therefore decided to use Math.floor() does double to String conversion method takes care of all double values automatically ? What is string representation of Nan or Double.POSITIVE_INFINITY or Double.NEGATIVE_INFINITY. See jcp.org for more information.How to convert formatted double e.g up-to 2 decimal point or 3 decimal point to String in Java ? Also large value of double is represented in exponential format, which string that will be returned. JSR 354: Money and Currency API, is also being developed in the Java Community Process. The Joda Money library is a Java library for handling currency. In my work as a consultant, I’ve seen most companies handle currency using the Java BigDecimal class, and others create their own custom currency classes, which are typically wrappers around BigDecimal. This recipe falls back to the Java approach for printing currency and other formatted numeric fields, though of course the currency solution depends on how you handle currency in your applications. Scala> val de = Currency.getInstance(new Locale("de", "DE")) This approach handles international currency: $123,456.79 Formatting international currency Scala> val formatter = įormatter: = println(formatter.format(123.456789)) Res0: String = 10,000.33 Formatting currencyįor currency output, use the getCurrencyInstance formatter: 
Scala> val formatter = įormatter: = formatter.format(10000.33) You can handle floating-point values with a formatter returned by getInstance: Res2: String = 1.000.000 Formatting floating-point numbers
Scala> val formatter = (locale)įormatter: = formatter.format(1000000) You can also set a locale with the getIntegerInstance method: Res1: String = 1,000,000 Setting the locale Scala> val formatter = įormatter: = formatter.format(10000) Res3: String = 003.14 Handling commas in numbersĪ simple way to add commas is to use the getIntegerInstance method of the class: If you’re using a version of Scala prior to 2.10, or prefer the explicit use of the format method, you can write the code like this instead: Res2: String = 003.14 The 'format' method Basic formattingįor basic number formatting, use the f string interpolator shown in Recipe 1.4 of the Scala Cookbook, “Substituting Variables into Strings”:Ī few more examples demonstrate the technique: Scala FAQ: How can I format numbers and currency in Scala, such as to control the number of decimal places and commas in the values, typically for printed output.
