In math context you can actually use ternary syntax:

    $(( x ? y : z ))

But I think you're actually looking for this:

${NAME-WORD}
${NAME:-WORD}
     If NAME is set, or in the second form is non-null, then substitute
     its value; otherwise substitute WORD.  In the second form NAME may
     be omitted, in which case WORD is always substituted.

So e.g.

    local num_files=${1:-10}
    local where=${2:-./}
