The float is 4 byte. So, by assuming platform is 16-bit, 2^(4*16) = 18446744073709551616
answer/2 = 9223372036854775808.
So, how it will be 3.4e38?
answer/2 = 9223372036854775808.

3.4e+38 means 3.4*10^38.
After e if it is '-' then we will write as;
3.4*10^-38.
After e if it is '-' then we will write as;
3.4*10^-38.
