1. How do I convert an answer to Standard Form using the following calculator?

http://www.amazon.co.uk/Casio-FX-991...tp_s2_edpp_url

In Physics calculations, I sometimes get big numbers like 3000000, and I prefer not to waste time counting the number of 0's (I could also miscount accidentally).. If I press the S <--> D button nothing happens. There must be a way to convert an answer to standard form?

Thanks

There may be a special button or perhaps you can set up the calculator to show standard form. However, one way is to use common sense to trick the calculator. Multiply by one followed by six noughts, this may result in the calculator displaying in standard form and THEN subtract 6 from the index. If this does not work then repeat and this time subtract 12 from the index.

If the number is small, then divide by one followed by 6 noughts, and ADD 6 to the index.

I suggest always using a million then you will remember to adjust the index by 6, or 12 etc

on your calculator, theres a button called ENG... after you have the answer, press that button
for example... type 1000000 into the calculator, press the = button, then press ENG

that s-d button is probably just for converting between decimal and fraction/mixed fraction...

Thanks! I think I will go with the ENG button method (as its simpler). steve2005 I tried +rep you but it says I have reached the limit..

Btw whoever negged me, I don't care lol

I think ENG gives answers like x times 10^3 , or x times 10^6 , or x times 10^9 I don't think ENG is standard form . See below

ive noticed the multiples of 3, which i find annoying...

i assume this may be because standard form also means standard units need to be used when appropriate

i.e.

10000m could be 1x10^4 m (which i would personally like)
but then you could also just do 10x10^3m and since 10^3m is 1km, you can easily use standard units if you memorised them (main ones usually go up in multiples of 3 i.e. terra (12), giga (9), mega (6) kilo(3), apart from small ones near index 0 i.e. deci (cant remember, think thats either 2,-1, or -2).

so 10000m = 10x10^3= 10km

what i do to get around this is just press eng, then divide/multiply by a couple of 10's and add/subtract said couple onto the index

that is quite useful, though its a bit awkward trying to remember mode set ups in a timed exam, id rather stick to my dividing/multiplying by 10 haha

id imagine it would be fine for me to use in coursework though, thanks

What is the difference between the two? Also which one is the original setting? (as I wish to return to that setting)

Thanks
13. Guys I'm confused. I type 55500000 into calc then ENG it but it gives me 55.5x 10^6. So what exactly is the ENG button then if it's not standard form?
