Hi!
Did you try to input "3e4" in the command window? What happens?
Also try
3e1
3e2
3e3

david's and Simon's answers are sufficient already.
While the definition is obviously clear and a common standard in nearly all programming languages, do you find it in Matlab's documentation?
What about 1E2, 1E-2 .1E-02, 1.e+2, 1.1e0, 2e2345678, 2d3, 3D4? The technical support stated, that only the formats supported by format are supported with a guarantee. But sscanf and the parser of M-code works for much more styles. It would be useful to document this fundamental detail.
