How to get the answer in binary?

Here is the question:

Write a function m-file called to_binary.m that simply converts a single number into a string representing the binary form of that number. You can reuse to_binary.m to calculate the mantissa and exponent + bias terms.

 >> to_binary (10.25)
 a n s = 1010.01

 >> to_binary ( -65)
 a n s = -1000001

I know how to convert the number into binary but I don't know how to display them like this : "a n s = -1000001". Please help!
