Variablen Bug of Float. & Double.MIN_VALUE!

[BinkanSalaryman]

I discovered this when I made a class called FloatBuilder (for typing floats into a textbox):
The minimum value of float and double are bigger than zero! That just can't be true...

Code:

        System.out.println("MAX: " + Double.MAX_VALUE);
        System.out.println("MAX < 0: " + (Double.MAX_VALUE < 0));
        System.out.println("MAX > 0: " + (Double.MAX_VALUE > 0));
        System.out.println();
        System.out.println("MIN: " + Double.MIN_VALUE);
        System.out.println("MIN < 0: " + (Double.MIN_VALUE < 0));
        System.out.println("MIN > 0: " + (Double.MIN_VALUE > 0));
        //Works for Float, too

Console Output:
MAX: 1.7976931348623157E308
MAX < 0: false
MAX > 0: true

MIN: 4.9E-324
MIN < 0: false
MIN > 0: true

It's not a bug, it's a feature! 😉

A constant holding the smallest positive nonzero value of type double, 2-1074. It is equal to the value returned by Double.longBitsToDouble(0x1L).

Does that mean I have to write

-Double.MAX_VALUE

to get the smallest value?

Yes.

this is actually one of the best (meaning: meanest) questions to ask an applicant during an interview....
