How can i convert Integer value to decimal value?

i have an Integer value:

Integer value = 56472201;

Where the value could be positive or negative.

When I divide the value by 100开发者_Go百科0000, I want this result in the form 56.472201 but instead it gives me just the quotient. How am I able to get both the quotient and remainder values?

cast it to float and then do it:

int i = 56472201;

float j = ((float) i)/1000000.0

Edit: Due to precision(needed in your case), use double. Also as pointed by Konrad Rudolph, no need for explicit casting:

double j = i / 1000000.0;

You have to convert the value to a floating point type first, otherwise you will be doing an integer division.

Example in C#:

int value = 56472201;
double decimalValue = (double)value / 1000000.0;

(The cast is actually not needed in this code, as dividing by a floating point number will cast the value to match, but it's clearer to write out the cast in the code as that is what actually happens.)

If you divide an int by a double you will be left with a double result as illustrated by this unit test.

@Test
public void testIntToDouble() throws Exception {
    final int x = 56472201;
    Assert.assertEquals(56.472201, x / 1e6d);
}

1e6d is 1 * 10^6 represented as a double
