Calculator for EECS?

<p>I've heard that most tests don't allow for calculators, but do you guys recommend getting a calculator for checking homework? I'm considering a TI-89. Does anyone have experience with this? My intended major is EECS.</p>

<p>Unless you need graphing capability in your calculator, the Casio fx-115 ES will do every thing you need it to do and only costs about $17.</p>
