printf format for double

[Joachim Schmitz]

Is it possible to print a float or double in exponential form with a 0
before the decimal point?

E.g. 0.1234567E+00 rather than 1.2345670E-01 (using %14.7E) ? As far as I
understand the format specifies in n1256, this isn't possible, is it?

No, there is no way to convince printf to do that. You could
post-process sprintf's output into that format, though.
