If you mean a handheld calculator for engineering school/work, my top picks are:
The TI-36X Pro is probably the safest recommendation, especially in the U.S. It has:
It's also a particularly good choice if you expect to take the FE/PE exams.
I'd choose the fx-991CW if you prefer Casio's interface. It has 500+ functions, a high-resolution display, matrices, vectors, calculus, statistics, spreadsheet functionality, and engineering notation. Casio itself lists it as its advanced scientific calculator.
If your courses actually require graphing, step up to something like the Casio fx-9750GIII or TI-84 Plus CE. But I wouldn't spend the extra money on a graphing calculator unless your courses require one.
My recommendation: If you're an engineering student in the U.S., buy the TI-36X Pro. If you like Casio calculators, get the fx-991CW instead. Both are more than capable for typical engineering coursework.
If you tell me your engineering major (mechanical, electrical, civil, chemical, etc.), I can tell you which one I'd buy specifically for that major.
The best calculator for engineering depends entirely on whether your priority is raw computing power or exam compliance.
