How do I change my Casio FX 991ES to decimal?
If you enter the operation 14÷9 into the Casio fx-991ES PLUS C, you'll just as likely see 14/9 on the screen. If you want the decimal, just press the SV60;D key. You can keep pressing the SV60;D key to toggle through various formats of the answer.
Please respond to my effort to provide you with the best possible solution by using the "Acceptable Solution" and/or the "Helpful" buttons when the answer has proven to be helpful.
