Function doesn't work
Hello, and here's my problem:

I can't get my function to do what I want. When I call my function get_from_A_to_F I give it an argument $remainder. I want my function to substitute a number higher than 9 to a specific letter. If the argument is equal to 10 than it should change it to "A". However it still leaves it as a 10. What am I doing wrong here?
Code:
#!/bin/sh

get_from_A_to_F() 
{   
    case $1 in
        10)  $1="A"
        ;;
        11)  $1="B"
        ;;
        12)  $1="C"
        ;;
        13)  $1="D"
        ;;
        14)  $1="E"
        ;;
        15)  $1="F"    
        ;; 
        [0-9]) $1=$1
        ;;  
    esac
    echo $1
}

read number
string=""
index=`expr index $number "."`
if [ $index -eq 0 ]
then
    integer=$number
    fraction=0
else
    integer=`expr substr $number 1 $(expr $index - 1)`
    fraction=`expr "$number - $integer" | bc`
fi
result=$integer
while [ $result -ne 0 ] 
do
    remainder=`expr $result % 16`
    get_from_A_to_F $remainder
    result=`expr $result / 16`
    string=$remainder$string
    #echo $string
done
