When the calculator (in this case Casio fx....) Look for the "a b/c" button on the key pad. For example 1.5 becomes 3/2 or 1 1/2

SOURCE: converting decimals to degrees on a casio fx-83es calcualtor

if you mean degrees like the degree/minute/second thing: lets say you have 24.12 there is a button that has a dot, and 3 commas (it's located next to the negative button) that will convert that number to degrees. input your decimal, press the equal sign, and then press that degree button and it will convert 24.12 to degrees, minutes, and seconds. the solution is 24 degrees, 7 minutes, and 12 seconds.

SOURCE: Hi, I have a Casio calculator fx-991MS giving me wrong answers!

Hello,
I am only looking for a plausible cause of the error, because I do not believe your calculator can make such a mistake. I think you accidentally activated the Exponential display format and did not pay attention to the small, raised -03 that came at the end of the number displayed. It is a common mistake for those not very familiar with Scientific or exponential notation.

Let us try to reset your calculator to the normal (floating point) format.
Press the [MODE] key a number of times until you reach a screen that has FIX, SCI, NORM and under each one a number (FIX 1, SCI 2), Norm 3). To have the number of decimal place you gave in your result (4 decimal digits), you press 1 to select Fix then 4.

Be aware that scientific calculators usually stop displaying results in floating point format ( 0.0000045 ) if the number is smaller then 0.001. So basically, 0.00099 will be displayed as 9.90-04, -04 being raised above the level, and in smaller size.

Hope it helps.

If the result is already calculated and displayed, press the [S<=>D] key It will convert a fraction or radical to decimal. This is always possible. If the result is decimal it may be converted to a fraction or a radical (Not always possible).

If the expression to be evaluated is still in the command line and you have not pressed the [=] key, you can force the result to be displayed in decimal format by pressing [SHIFT][=] instead of just [=].

More permanently. If you do n o care for fractions and radicals, set the Input/Outpout mode to LineIO. To do do press [SHIFT][MODE] to access the (SETUP) screen and select [2:LineIO]

Cant get answers in decimal format, I would like to set up my casio fx83es so that the answer is in decimal format all the time.


Hello,
To make sure that results are always in decimal format, put a decimal mark (point) at the end of one integer.
ex: 1./2 or 1/2. or 1./2. display as 0.5, so does 1. + 1/2
To convert from decimal to fraction and from fraction to decimal press a b/c
To convert from proper to improper fractions use [SHIFT][d/c]
Hope it helps.

Alternatively, If you multiply or divide two integer numbers put a decimal mark at the end of one of the numbers (any one). The result will be displayed in decimal format.

You may be lucky and recover a fraction you have just converted into decimal format, but you cannot just write 0.333333333333 and expect the calculator to convert it to 1/3: The true fraction 1/3 has an infinite number of 3's after the decimal mark.
