Asking about mantissa and exponent in Java

[scracker]

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?

it would round to 16 digits
