2.2e-308 and1.8e308 are numbers wrote in exponential notation.
Exponential notation is a way of writing large numbers without having to write out a lot of zeros, for example, 1,000,000,000 can be written as 1.0E9.
The number followed the E is called the exponent and it indicates how many places the decimal point must be moved to change the number to the normal decimal notation.
The exponent can be positive or negative; the exponential number 6.35E-5 is equivalent to 0.0000635 in decimal notation....
