# Is there a term for numbers like 0.5, 9.15, 4.22? [duplicate]

I know that in some country, there is a term for numbers like

``````0.5, 9.15, 4.22
``````

I mean number with dot(.) in its expression.

I sought for the term in English. It was

Decimal Number

But the term "decimal number" means just base-10 number.

``````3, 19, 277
``````

Above numbers are in base-10 form, so they are decimal number (even though they do not have dot(.))

Is there a exclusive term for numbers with (.) in its expression ?

• Decimal can also mean 'expressing part of a whole number as a decimal rather than a fraction' - 1.5 as opposed to 1 1/2. Commented Oct 2, 2021 at 14:29
• You seem to be looking for a classification that includes 3.14, 5.0, and 0.0 but excludes 5 and 0. In math, 5 and 5.0 represent the same number. In computer science, though, the former is represented by an integer and the latter by a float. There are some inherent difficulties with this kind of classification. So two questions: are we talking math or computer science? And does 5.0 count as a decimal number, or not count because it's also an integer? Commented Oct 2, 2021 at 14:40
• @rajah9 - Along with floating point there is also fixed point
