No. 1e4. e/E does not mean superscripted or "raised to the power of."
It's for scientific notation, it means "times 10 to the power of..." So
it is sensible to say 1.43e7 to mean 14300000, not to mean 1.43^7. At
least, that's how I see it in most computer notation; it may have been
different in Fortran.
