Ok, thanks. Not fluent enough in C to be able to help. But I wrote a function that basically does the job, although some extra parameter could be added to control the formatting:
create function sci (x float) returns text as $$ select regexp_replace(to_char(x,'9.99EEEE'),'(.+)e(-*)(\+*)(0*)(.+)',E'$\\1\\cdot 10\^{\\2\\5}$') $$
Example:
select sci(0.003337),sci(5678);
sci | sci
----------------------+---------------------
$ 3.34\cdot 10^{-3}$ | $ 5.68\cdot 10^{3}$
(1 row)
