Comparing double values for format in java?

I need to comparing some double values for format

For example :

double a = 18.0;
double b = 18.00;
double c = 19.0;

a == b //Comparing for format => False
a == c //Comparing for format => True

Is there any method or idea?

Maybe you can use Decimal: 

java.math.BigDecimal.equals(BigDecimal val)

So 

BigDecimal bg1, bg2;

    bg1 = new BigDecimal("20.0");
    bg2 = new BigDecimal("20.00");

with equals bg1 and bg2 Are not equal in value and scale

"==" simply you wont be able to do that, use OOP, create some class and pass these two values, convert both to string, than compare, return value accordingly

There is literally no difference between a and b. double values don't know their format; they're just numbers.

If you stored them as strings, that would be different, but a and b are exactly the same values.
