Binary / Hexadecimals help?

hello, I just have a few questions:

how do you convert a decimal number such as -2.015E32?

I know how to convert regular numbers, but I have no idea how to deal with the exponent....

Also, what does it mean if a hexadecimal number is in form:

0x9D8EE2AB

I mean, i get the 9D8EE2AB part, but what is the 0x that is in front of it?

any help would be greatly appreciated!

Update:

how do you convert the decimal number -2.015E32 into a binary number is what i meant to ask
