I checked in the manual and found that this calculator does not support Base-N calculations. On the FX-991ES Plus, which has a Base-N mode, fractions , exponents, and other floating points are not supported. The non-integer part is chopped off.
What kind of a number is this? DMS representation? 36.6 =366/10=183/5 If calculator is in MathIO Mode, the calculator displays the result as a fraction. To toggle back and fort between fraction and decimal representation press the [S<>D] key just above the red DEL key (FX991 ES)
Dinary? Never heard that one before. What is a dinary number? Anyway your calculator cannot perform the operations. The Casios can work in Binary (base 2), Octal (base 8), Decimal (base 10) and Hexadecimal (base 16). Some Sharps can do calculations in base 5 (pental).
The little L is the way to separate the numerator from the denominator. That is the old way of writing fractions. If you want the stacked representation, switch the display mode to MathIO.
Press Shift Mode to get to Settings, then enter the number corresponding to MathIO.
The calculator has two Input/Output modes: MathIO and LineIO.
LineIO LineIO is the old way of entering numbers in calculators and results are always displayed as decimal numbers. Some calculators have a fraction feature and would convert a fraction to a decimal number and back.
MathIO In MathIO you enter expressions as you would by hand or as you see them written in textbooks. In this mode, results are by default displayed as fraction or fractions/ radicals. Conversion To convert the fraction/radical to decimals you just press the [SD] key. If you press again you cycle through all the available display formats. So you can (if you want) use the MathIO to manipulate expressions and convert only the last result to decimal. By the way, fractions and radicals are generally more accurate than their decimal representations.
SetUP If however seeing fractions and radicals is too painful, just set the LineIO as your default mode. To do so press [SHIFT][MODE] to open (SETUP), then select [2:LineIO]
Press MODE 4 to enter the BASE-N mode. If the display doesn't say Dec, press SHIFT DEC (the x^2 key) to set base 10. Enter the number to convert. Press SHIFT BIN (the log key) to switch to base 2.
Each time you switch the base the current value is redisplayed in that new base.
