any figure upon zero is INFINITY, then why the calculater locks showing E in display window, why is it so?

Question

nobody cld defined perfectly about the term INFINITY, can i get the perfect answer for this question? is it possible to define infinity in as close as possible?

Answer 1

E means error. The calculator cannot perform those calculations as they may be undefined or more than the capacity of the calculator. By higher standard calculator, we can perform calculations with more accuracy. But some calculations like 0/0, any number divided by zero cannot be performed by any calculator because they are undefined calculations.

Answer 2

Infinity is not so easily defined.
An one liner which may throw some light on the concept goes like this-
" Infinity is a number larger than the largest number u can think of".
This plays only for numbers.
Actually infinity is a RELATIVE CONCEPT,which means something which is infinite somewhere may be vividly finite somewhere else.
Do this:
Draw a long line on a paper ,now take ur eyes to a centimetre above it ,try to locate the ends of the line.u'll fail,the line is endless from this distance- i.e. it has Infinite length from THERE.
Now pull ur eyes up and look from well above.the line is completely and finitely visible.it is finite now.

In case of calculators (older types)- 1/0 operation displays the largest randomised number it can display.
Perhaps u see something like this: 6.7E2348
This means a number which is=6.7*(10 to the power of 2348)
However newer calculators are devised to show " Mathematical Error"in case the user asks for such an operation.This is because infinity is not defined for machines.

Answer 3

It is indeed possible to define infinity in a rigorous way in several contexts. However, there remain certain operations that are not allowed. Depending on the exact context, dividing a non-zero number by zero may or may not be one of them. Dividing zero by zero always is.

The main difficulty with dividing a non-zero number by zero is that we can't tell whether the result should be +∞ or -∞. In some contexts we only have +∞, and we can then say a/0 = ∞ when a is not 0. But 0/0 is still not allowed.

In terms of your calculator, it is designed to operate in the context of the real (or possibly complex) numbers, in which there is no such thing as ∞ and dividing by 0 is always an error, which it indicates with the -E- message.

(Note to deadlyfu: -E- does NOT represent infinity. It represents any sort of error, for instance ln (-1) which is an invalid operation in terms of the real numbers, but certainly does not correspond to infinity of any sort; in the complex numbers the answer is -iπ, for what it's worth.)

Answer 4

E can represent power of ten notation: 10 x 10^500 yields:1E501. The larger the number following E indicates the # of trailing zeros, infinity is approached in this way.

Edit: Assuming you are NOT trying to divide by zero.

Answer 5

the letter E is used to symbolise infinity.it is possible to show the words "infinity" instead .All that is required is appropriate designing of calculator

Answer 6

E = Error.

Just keep moving the decimal place until you don't get an anwer.
1/0.1
1/0.01
1/0.001
1/0.0001
and so on...
