Hi guys,
Don't know if this question belongs in the advanced or beginners
java section, so am putting in the intermediate section. Hope this is right, but please move if not.
I have a worry when it comes to floating point values loss of precision. Maybe you guys can help to substiate my worry, or provide a solution to it.
I'm writing a financial application that it working with decimal numbers. Therefore i can't use float or double. Use bigdecimal instead. I need to take 'a decimal value' to the power of 'another decimal value'.
There is the function Math.pow(double a, double b) that returns a double.
If I do this for example:
BigDecimal one = new BigDecimal("1.234");
BigDecimal two = new BigDecimal("1.5");
double answer = Math.pow(one.doubleValue(), two.doubleValue());
BigDecimal result = new BigDecimal(answer);
So my question is, will there be a loss of precision for the variable 'answer' when I call the Math.pow method?
Any comments?
cheers
