programming calculator with bash

[xiekke]

hi, i am trying to program a calculator,


**************************************************
#!/bin/bash

echo "(($1))"
************************************************** *
.. and that is my whole program, works fine wth integers, but with decimals it would show error, can any help with calculating with decimals?

Try:

#!/bin/bash
echo $1 | bc

See bc(1) for details.
