how to substitute ',' by '.' within awk script

Content of $4 is 0.500
$4 *= 0.5 results in 0,25 and leads to an additional value in VALUES clause
of INSERT statement (SQL).
0.25 is needed as result to INSERT into database correctly.

I start walking through the archives, but maybe someone can point to the
right direction meanwhile.

Thanks in advance
