Exponent mantissa form of real numbers

Hi,
I'm supposed to convert the following real numbers into exponent mantissa form:
a = 789.34
b = 0.0001
c = 400000000000
My first question is: what does exponent mantissa form mean? I've read something about binary online but I doubt that that's what we're supposed to do in this exercise.
My second question is how do I convert the numbers above into exponent mantissa form using matlab?
Any help is greatly appreciated!
Many thanks,
Dobs

Without seeing the actual wording of the assignment, I would assume this simply means "floating point notation". E.g.,
123.456 can be written 1.23456 x 10^2 or 1.23456e2
.0123456 can be written 1.23456 x 10^-2 or 1.23456e-2
You can use lowercase e or uppercase E for the exponent. What is the actual wording of the assignment?

Please show us what you tried. We can't guess what you did wrong. E.g., to use fprintf:
x = 123.456;
fprintf('%e \n',x);
The %e is the exponential notation format to use to print x, and the \n is a newline so the curser will move to the next line after printing x.
