Re: real number -> scientific C like string

CSciForm[x_] := NumberForm[ N[x],
	NumberFormat-> (SequenceForm[#1,"e", #3]& ), 
	ExponentFunction->Identity ];
Attributes[CSciForm] = {Listable,OneIdentity}

This works on the examples in the e-mail.  The NumberFormat trick is
given on p. 352 of the Mathematica book.  The attributes let you do
CSciForm[{3.123, 241.}].  I wrap N around x, because the exponent 
is always Null for NumberForm of an Integer.
