    Asking about mantissa and exponent in Java

    Hi

    In Java, as you know that a double number such as 1.564E15 has two parts:

    Mantissa: 1.564 and Exponent: 15. Mantissa can have up to 16 digits of accuracy.

    I wonder if a number like this would be correct as the
    definition above or not

    1.7976931348623157E308

    I think that its not valid cause the mantissa has 16 digits of accuracy while the mantissa of the one above has 17 digits. What do you think?
