Hello ranchers, can anyone tell me why this following code prints out this output->Infinity, -Infinity, 4.4E99?

{
Float f1 = new Float("4.4e99f");
Float f2 = new Float("-4.4e99f");
Double d1 = new Double("4.4e99");
System.out.println(f1);
System.out.println(f2);
System.out.println(d1);
}

Thanks

Basically, the value you are using is well within the range of a double (which has a max value of about 1.8e308), but well beyond the range of a float (which has a max value of about 3.4e38).
