not the most efficient way but it works in showing user input with case statement.

Code:

#!/bin/bash

y=1
echo -e "Choose Names as listed in the format below.\n \
1. mango\t2. tango\t3. rango\t4. exit"
read answer


while [ $y=1 ]; do
    case ${answer} in
    "[Mm][Aa][Nn][Gg][Oo]"|1)
        echo "mango"
        mode="mango"
        echo -e "Specify an Option\n1. add\t2. sub\t3. exit"
        read option
        case ${option} in
            "[Aa][Dd][Dd]"|1)
                echo "you chose add"
                ;;
            "[Ss][Uu][Bb]"|2)
                echo "you chose sub"
                ;;
            "[Ee][Xx][Ii][Tt]"|3)

round

ROUND(3)								 1								  ROUND(3)

round - Rounds a float

SYNOPSIS

       float round (float  $val, [int  $precision], [int  $mode = PHP_ROUND_HALF_UP])

DESCRIPTION

	Returns  the  rounded value of $val to specified $precision (number of digits after the decimal point). $precision can also be negative or
       zero (default).

       Note

	       PHP doesn't handle strings like "12,300.2" correctly by default. See converting from strings.

PARAMETERS

	      o $val
		- The value to round

	      o $precision
		- The optional number of decimal digits to round to.

	      o $mode
		- Use one of the following constants to specify the mode in which rounding occurs.
