Surds calculator wont show surds or rationalise them, just gives a decimal

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: i dnt kno how to get the decimals off

dude i just found it out press mode CLR at the top 3 times then press the # 3 at the botton
it should say (norm 1~2?) when it does press the # 2 and there you go!!!!!!!

Hello,
Use the [S<->D] key to switch between the two.
Hope it helps.

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

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.
