Hello, Hoping to get some feedback from someone more experienced here. I haven't dealt with the dreaded floating-point calculation before... Is my understanding correct that with Ruby BigDecimal types (even with varying precision and scale lengths) should calculate accurately or should I anticipate floating point shenanigans? All my va...
If you specify your ActiveRecord column type to be decimal, Rails will return that database value as a ruby BigDecimal object. My question is, when working with these fields and performing additional math on them, should I always use BigDecimal values in my calculations or are floating point values ok to use. I didn't know if it is a go...
Is there any way to convert a BigInteger into a BigDecimal? i know you can go from DEC to INT but i cant find a method to go the other way around in JAVA. thanks in advance. ...
Hi All, I have a BigDecimal currency value that needs to be converted to a 6 byte BCD value in cents with leading zeros for a lower level protocol I'm interfacing with. Anyone have any cunning implementations for doing this? TIA, Fred ...
I have a BigDecimal object, myNumber, with unknown length. For example: 12345678. I always want to divide this number by 1 million, so I do: myNumber.divide(BigDecimal.valueOf(1000000)) I get 12.345678. I want to display this as a string "12.345678", without cutting off ANY decimal places. So I do myNumber.divide(BigDecimal.val...
new BigDecimal("37146555.53880000").divide(new BigDecimal("1000000")).scale() This returns 10. But according to the API, the divide method: Returns a BigDecimal whose value is (this / divisor), and whose preferred scale is (this.scale() - divisor.scale()); So in this case, 37146555.53880000's scale is 8, and 1000000's scale...
I have a BigDecimal field amount which represents money. And I need to print its value in the browser in format like $123.00, $15.50, $0.33. How can I do that?

In my little project I need to do something like Math.pow(7777.66, 5555.44) only with VERY big numbers. I came across a few solutions: - Use double - but the numbers are too big - Use BigDecimal.pow but no support for fractional - Use the X^(A+B)=X^A*X^B formula (B is the remainder of the second num), but again no support for big X or bi...
I am trying to make a BigDecimal from a string. Don't ask me why, I just need it! This is my code: Double theDouble = new Double(".3"); System.out.println("The Double: " + theDouble.toString()); BigDecimal theBigDecimal = new BigDecimal(theDouble); System.out.println("The Big: " + theBigDecimal.toString()); This is the output I get? ...
I'm trying to read some BigDecimal values from the string. Let's say I have this String: "1,000,000,000.999999999999999" and I want to get a BigDecimal out of it. What is the way to do it? First of all, I don't like the solutions using string replaces (replacing commas etc.). I think there should be some neat formatter to do that job fo...
In my app, I handle numbers as BigDecimal and store them as NUMBER(15,5). Now I'd need to properly check on Java if the BigDecimal values would fit the column, so that I can generate proper error messages without executing the SQL, catching exceptions and verifying the vendor error code. My database is Oracle 10.3, and such errors cause ...
I just switched my Ruby version to 1.9.2, and the BigDecimal code works in Ruby 1.8 doesn't working anymore. Here is test code show what happened irb(main):001:0> require 'bigdecimal' => true irb(main):002:0> (BigDecimal.new("1")/BigDecimal.new("3")).to_s("F") => "0.33333333" irb(main):003:0> (BigDecimal.new("1", 20)/BigDecimal.new("3",...
How to convert from float to bigDecimal in java? ...
What is the difference between this two call? (Is there any?) // 1. new BigDecimal("3.53456").round(new MathContext(4, RoundingMode.HALF_UP)); // 2. new BigDecimal("3.53456").setScale(4, RoundingMode.HALF_UP); ...
Actually, I've found possible solution //returns true new BigDecimal ("5.50").doubleValue () == new BigDecimal("5.5").doubleValue () Of course, it can be improved with something like Math.abs (v1 - v2) < EPS to make the comparison more robust, but the question is whether this technique acceptable or is there a better solution? If so...
