Floor[Range[0, 100]*100/254] (* Paolo Xausa, Jul 16 2025 *)

PARI

a(n) = floor(n*100/254);

Formula

a(n) = floor(n/2.54).

Eric Desbiaux suggested (Apr 19 2008) that A047332(n)-A080686(n) =? a(n-1), but R. J. Mathar points out that this is only true for the first 23 terms and so is nothing more than a coincidence. - N. J. A. Sloane, Apr 26 2008
