Question

i have an array, a double array like…

Double my_array = new Double[] {6272640.0, 43560.0, 4840.0, 0.0015625, 4046856422.400000095, 40468564.223999999, 4046.856422400, 0.004046856, 1.0, 0.404685642};

and in my program i want to multiply each of that elements with some integer values…
which i accept through a variable n.

i had done it in my program as…

for(int 1=0;i<my_array.length;i++)
{
my_array[i] = n*my_array[i];
}

when i try to print the result, i gets value as exponentials…
like, 3.23E etc etc……

I need the result as double value up to 8 decimal points…

What should i do to get it

Answer 1

I had changed my double array to String array, like

String my_array[];
my_array = new String[] {"1.006944444","6.45160645160", "0.00000326701", "0.0076001595"};

// then used my for loop like

BigDecimal b1 = new BigDecimal(n);
for(int 1=0;i<my_array.length;i++)
{
BigDecimal b2 = new BigDecimal(Double.parseDouble(my_array[i]));
BigDecimal result = b1.multiply(b2);
System.out.println(result.doubleValue);
}

just check it yourself. as i had just described the logic, my for loop had much more to do..
