Raj,
There is not a method that truncates a double to a certain
precision. Check out this link for an explanation on Performing Exact
Calculations With Floating-Point Numbers
http://developer.java.sun.com/developer/JDCTechTips/2001/tt0807.html
Basically, can either use the BigDecimal class that supports arbitrary
precision numbersinstead of the double type or you can write a method that
rounds a number to the desired precision for you.
ie
/**
* Trim a double value to two decimal points
*
public static double trim(double d)
{
BigDecimal bd = new BigDecimal(d);
return bd.setScale(2,BigDecimal.ROUND_HALF_UP).doubleValue();
}
