runif will put "real" numbers in 'a'. It is highly likely that any of them will be zero, and in any case they are not "digits" (though in their decimal representation many of them will have at least one "0" in the string of digits for each one). So it is not clear what you mean by "the first non-zero digit of any vector". Please clarify!
