I just bought a CASIO DV-220 dual calculator. I can't figure out how to set the decimal. Example: 565 to 5.65 I'm probably going to feel silly because I'm sure it's easy. I've been able to do this before but this is new.

Sorry I never got a mail when you asked the question, I guess you've solved it by now...

any for anyone else who may have the same problem..you have fix selected(significant figures)

press the mode button top right, repeatedly until it displays Fix sci norm,
press the number underneath Fix which is probably 1
then press the number of decimal places you would like Between 0 to 9 yours at the moment is obviously set to 0

Sorry for being so late....

Doubt you're still having this problem as its been months....figured id post for people who stumble across this from google.

Click on the shift button in the top left, then select the mode buttom (second from top right), then press the number 2. This should switch the calculator onto linear and will give you answers with decimal points.

Hello,
Since you bent on deactivating the very features that make your calculator so versatile and so powerful, here it is.
Press [SHIFT][MODE][2:LineIO] and you will see no more fractions, nor radicals etc. You asked for it.
Hope it helps.

Testimonial: "I bought the calculator because it was on sale and I like Casio calculators; not for its fractional abilities. I can easily switch it back now. Thanks"

To convert a single result to decimal, press the S--D key. To have all results come out in decimal, press SHIFT MODE 2 to select the LineIO mode.

Press SHIFT [MODE] to bring up the mode screen. Press 8 for NORM, then 2.
Bear in mind that if the magnitude of the number is too large or too small the calculator will switch to scientific notation anyway. For example, if a number has twenty leading zeros then it won't fit on the display unless it displays it as a power of ten to the negative twenty.
