i need a calculator script, which it can calculate even float numbers , and if its possible of course i want to make more than one operation at once
for example i want to calculate 5.6 + 2.3 / 6 * 7 .

yeah i have already read your page .
i have followed what you do exactly say .unfortunatly my teacher won't accept it because she insisted to write a script which it implements a calculator
i have done a script by my self but it doesn't allow to calculate float numbers and even the division opertion it didn't give the correct answer without commas

#!/bin/bash

echo -n "Enter a number:"

read n

echo "Calculations (x,-x, / x * x)"
echo "type = result without having to leave the calculator and proceed to do the calculation"
echo "type end to exit the calculator"
echo "======================================"
echo "==>"$ n
op = ""

while ["$ op" != "end"] do
while ["$ op ! =" = "] & & [" $ op " !=" end "] do
echo -n "==>"

read op





if ["$ op"! = "="] & & ["$ op"! = "end"];
Then
eval "let n = n $ op"



fi


done

if ["$ op" = "="];
Then

echo "$ n"
fi

if ["$ op" != "end"];
Then
echo -n "==>"
read op
eval "let n = n $ op"
fi
done
echo "======================================="
echo "$ n"

i resolved my problem.thank you anyway

I usually use this one:

guess we need to change this url to "comeaskushowtodobashhomework.org"...
