20 Most Recent Casio DR-250HD Calculator Questions & Answers

Does the E code look like 10.8372487489E12?

If so, the calculator is either set to scientific notation mode OR the result was an answer that was too big to display on the calculator, so it converted it to scientific notation. To convert from scientific notation back to regular notation, move the decimal to the right by the number of times after the E. In this case, the number after the E is 12, so we have to move the decimal to the right 12 times. In this case, I get the final answer as 10 837 248 748 900.

Good luck.

Any questions, let me know.

when this happen just replace the batteries or turn the calculator upside down. find the reset hole and use thin pin. an office paper clip stretched will suffice. insert it inside the hole and press to hear a click sound. that is how to reset a calcolator.
