Decimals screw up the escape sequence and the cursor will not get set. Right now this only affects setting the cursor for drawing "Welcome to FreeBSD" -- the resulting number after our (x+(w/2)-9) calculation gets output as "14.0." This should be fixed at the interpreter level, rather than here, but this is not a widespread problem at the moment so we'll fix it up in further work.
