    and this way is better still, since we're gonna get the wrong
answer
    if our input is greater than 25, anyway:

    movf    num,w   ;w = num
    addwf   num     ;num = 2 * num (if num < 128)
    rlf     num,w   ;w = 4 * num (if num < 64)
    addwf   num     ;num = 6 * num (if num < 42)
    addwf   num     ;num = 10 * num (if num < 26)
