Ze Values? HELP

[davesparks]

well all i can say is the onsite guide should write it as 0.80, thanks tho that makes alot more sense than the regs

Why should the write it as. 0.80 if they mean 0.8? The numerical value is the same but the implied accuracy is not, 0.80 implies greater accuracy than value than 0.8

with maths like that, you'll never make a scouse wheel thief. you'd nick1 and say it was more than 4!

0.15 is not higher than 0.80 if you look at it that way

fart?..... follow through, more like.

Thats 1 big brain fart....

i think the op is overpaid rather than his namesake

Stop making out that scousers are thick

no need, you scousers don't need a helping hand to prove that to the rest of us

0.80 implies greater accuracy than value than 0.8

Could it be that it was 0.8 exactly, with the zero dropped as it would be irrelevant, to the outcome calcs.
Sorry I'm trying to get my head around this, not disrespecting your post.

am new to testing so am sure i will make mistake, thats why i joined this site to get help from experienced electricians not to be bullied

Welcome along, you will find this site extremely useful, just banter nothing else enjoy it.

The zero is relevant to the outcome of the calculation as it will have an impact on its accuracy.
0.8 x 0.320 = 0.3
0.80 x 0.320 = 0.26
0.800 x 0.320 = 0.256

0.8 is a value anywhere between 0.75 and 0.84 wheras 0.80 is a value between 0.795 and 0.804

...Your calculator needs re-calibrating...:icon12:

ok, so this is the second version of my reply after noticing the wink at the end of that, this version being far more polite

Yes mate. If the 2nd, 3rd 4th etc decimal place is not required, dont need to use it or it would become 0.800000 or 0.8 X 10 to the power of minus 6 (level 3 maths, you will see)

^^ that is correct isn't it gents? Been a long time since writing this form of equation and it does not look right?

This is getting too in depth,anyone know if my maths are right,I seem to keep getting e=mc squared

Yes you do, the number of decimal places displayed is significant in any calculation as it defines the accuracy of the end result. There's no point using a good quality tester which reads to 2dp then only recording the result to 1dp, you might as well use a less accurate tester.

Oh and 0.8 x 10 to the -6 would be 0.000008

(Or it might even be 0.00000008, thanks Mr styrofoam)

Special!

Special!

Relatively speaking lol

 

[davesparks]

I'm glad you got that!

I'm laughing my man ----- off right now :rofl: What a simple mistake! Knew it did not look right when I typed it, it's been a long day.

Well done for positioning your point

Sorry, I mean pointing out your position

You might want to edit that! :smilielol5:

Yeah, I was still closer than Paul though

Yeah, I was still closer than Paul though

No your not! 0.8 x 10 -6 =2!!!! :rofl:

It's to late for this, I'm off to bed lol.
