Terve/priviet, nice catch, here's an update:

ths () {
    local value=$1
    local denom=${2:-16}
    local whole=$(( int(floor($value)) ))
    local rest=$(( $value - $whole ))
    local frac=$(( int(rint($rest * $denom)) ))
    if (( $frac > 0 && $(( $frac % 2 )) == 0 )); then
        local new_denom=$(( denom / 2 ))
        ths $value $new_denom
    else
        local frace
        (( $frac > 0 )) && frace=-${frac}/${denom}
        echo ${whole}${frace}
    fi
}
# $ ths 2.0
# 2
# $ ths 1.75
# 1-3/4
