selecting specific line numbers

I have a file Which contain 50,000 lines of floating values. I need to select only data every 100 lines. Is there any command available in awk programming?

Many thanks in advance.

Alternative, sed solution:

sed -n '100~100p' file

More generally, the expression A~Kp means print every Kth line starting with line A.

To print lines which are numbered 100, 200, 300... you can do:

awk 'NR%100==0' inputfile
