[Solved] PHP printf adds something after formatted string

Question

I got it.

I wrote:

echo printf(...);

instead of just:

printf(...);

After string produced by printf() i got that string length, which is value returned by printf (in fact – added number was 9 in case of 123.45 value, in 20.4 case it was number 8).
