When is O.5 not one half?

Answer 1

when you put an O in front of it instead of a 0.

Answer 2

When it's the product of O and 5.

Answer 3

Mathematically 0.5 will always equal 1/2. Unless you are only talking about the 0 and 5 which in case would be when the decimal is removed.

Answer 4

In any base other than 10

Answer 5

The old professor says: It will not be one-half if you are using a base system other than 10.

Answer 6

In every other infinite possible instance except when it is half of 1.

It is not half of 2
It is not half of 3
It is not half of 5.7685
etc etc etc.

It is an operator that when multiplied with a number returns half the original sum.

Answer 7

It is one half - it cannot change Except when you are using different system of numbers.
-- Mathematician
In degree of temperature, I haven't heard of one half degree, have you?
-- Physicist
No of course not a half! How can you find the word 'half' in it?

Answer 8

When you treat that point not as a decimal but as a multiplier. Then we can read it as 0 multiplied by 5 and that will be a zero.

Answer 9

0.5 can easily be shown to NOT ALWAYS be one half:

Consider the following:
What is the answer to the following: 2.5 - 2.0 = x
Obviously, x = 0.5.
Obviously, that is not one half of anything -- it is actually 20% in this example.

Answer 10

you type the letter O instead of the number 0 (zero) and the letter O does not relate to anything in numerics.
