SOURCE: calculator won't show decimal places

Haven't heard of it giving nearest whole numbers before. But have you tried pressing SHIFT and then SETUP (upper right hand corner next to ON button) and then pressing 2 (LineIO)? Or perhaps you're in different MODE?

SOURCE: answers in decimals

The calculator has two Input/Output modes, MthIO and LineIO. In MthIO the results are displayed as fractions or as radicals or a mixture of fractions and radicals. What it means, is that in MthIO the calculator does exact calculations. Radicals in denominators are gotten rid of by rationalization, fractions are reduced to the same denominators before addition or subtraction. Fractions are reduced to simplest form.

In LineIO all results are displayed as decimal numbers.

If a result is exact (fractions and radicals) it can be changed to decimal form by pressing the S To D key, the one above the DEL key.

MthIO is the default IO mode. To set it, press SHIFT MODE and select 1:MthIO. To set LineIO as the IO mode, press SHIFT MODE and select 2:LineIO

SOURCE: Hi there, I have a

The calculator can't identify that this is a surd unless you input it as a surd, ie as 3/(4*sqrt(5))= when it will then show the equivalent form 3*sqrt(5)/20 (obtained by multiplying top and bottom by sqrt(5)) and you can swap between the two forms using the S<>D button. Even adding the next 4 decimal places (hidden) won't allow the calculator to identify the underlying surd as this is simply too complcated a calculation.

On my casio fx-82au plus calculator it won't


The capability of these calculators to handle irrational numbers in radical form is limited to square roots. Roots of index other than 2 are always displayed in their decimal representation.
If the calculator IO mode is set to MathIO, square roots will be displayed with the radical symbol. More complicated expressions with square roots might not be preserved and will be given as decimal numbers.

Hi there, I have a Casio fx-991ES, and my calculator doesn't seem to be converting decimals in surd form... i.e. 0.3354101966 was the last number I typed in that didn't work... That, in surd...


The calculator can't identify that this is a surd unless you input it as a surd, ie as 3/(4*sqrt(5))= when it will then show the equivalent form 3*sqrt(5)/20 (obtained by multiplying top and bottom by sqrt(5)) and you can swap between the two forms using the S<>D button.

Calculator wont show decimals


To convert a single value to decimal, press Diamond then ENTER. To get them all that way, press MODE then F2. Scroll down to Exact/Approx and change it from Auto or Exact to Approximate.

Decimals wont show


Hi,
You need to change the display format.
Press the [MODE] key a certain number of times until the screen displays Fix, Sci, Norm on one line, and 1 2 3 on the next line, with 1 under Fix, 2 under Sci and 3 under Norm.

Press 1 (Fix) followed by a number (1,2,3, etc.) This second number will set the number of decimal digits. In other words, if you press 1 (Fix) 3 all your results will have 3 decimal digits. If you choose 0, your results will not show decimals.

Hope it helps.
Thank you for rating the solution.
