Format of BigDecimal number
bigdecimal, java
Solution
You could use the String constructor of BigDecimal. It preserves the scale (which is what you want).
BigDecimal val = new BigDecimal("0.20");
See http://docs.oracle.com/javase/1.5.0/docs/api/java/math/BigDecimal.html#BigDecimal(java.lang.String)
Problem
``` BigDecimal val = BigDecimal.valueOf(0.20); System.out.println(a); ``` I want to store in val a value `0.20` and not `0.2`. What I can do ? I dont think I can use `NumberFormat` in this case, when I use `NumberFormat` I must know what the length of my decimal number is! I can have 0.20 or 0.5000, I don't know the exact length of my decimal number, so I cannot use : ``` DecimalFormat df = new DecimalFormat("#0.00"); ``` or ``` DecimalFormat df = new DecimalFormat("#0.00000"); ``` maybe I have just 2 numbers after point or 5 numbers or more, and this program doesn't work: ``` BigDecimal a = BigDecimal.valueOf(0.20);//i give an example of 0.2 i can have 0.98...0 System.out.println(a); NumberFormat nf1 = NumberFormat.getInstance(); System.out.println(nf1.format(0.5000)); ```
