How can I describe the following numbers?

0.2
0.4
0.6
0.8

Can I call them "even tenths"?

For example:

"If the maximum value in the data set is 1, then the values displayed in the bar graph are the ______." I am pertaining to the numbers above.

    Typically, these are called "fifths." – Tatpurusha May 19 '14 at 3:23

    Your question in the text is different from your question in the title. Are you looking for what to call those four numbers? If so, yes they are fifths of a unit. Or are you looking for a way to describe an even first digit after the decimal point (as the title says)? The entire number or the first digit? Why don't you give a sentence showing how you would use the answer X that you are looking for? – Drew May 19 '14 at 3:29

    @Tatpurusha The argument whether they are actually "tenths" or "fifths" is not much about the English language. – Kris May 19 '14 at 5:59

It just so happens that there is an answer to this very question on the math stack exchange.

Can decimal numbers be considered “even” or “odd”?

Reading through the answers there, I think it's safe to say that a decimal number can not be called even (or odd) unless you are prepared to get into some serious math and/or philosophy.

You don't need to add even into your description.
The first place that comes after the decimal point is always just a tenth.

0.2 - two tenths, also shown as 2/10 (or one fifth, 1/5)

0.04 - four (one) hundredths

0.006 - six (one) thousandths and so on

If your number looked like this - 0.41 - then you would simply state that it is zero/nought-point-four-one or four tenths and one hundredth. It is not referred to as an uneven tenth.
