title: using negative exponents with bc in Bash
body: <p>I'm having a difficulty with using negative exponents in the program <code>bc</code> in Bash. If I execute <code>echo "2*1.86929*10^05" | bc</code>, I get a result of <code>373858.00000</code> while if I execute <code>echo "2*1.86929*10^-05" | bc</code>, I get a result only of <code>0</code>. How can I get better accuracy when using negative exponents?</p>
