- Write out the whole number normally. For the part of the number before the decimal point, write it out as you usually would.

- Note that you don't write "and" if the number is less than one. ...
- Write the numbers after the decimal point as a whole number. For example, write .052 as “fifty-two thousandths.”
- End with the place value of the last digit. For example, the number 0.003 is three thousandths, because 3 is in the thousandths place.

How to represent a number?
For instance, $sqrt2$is a number, which is written neither in decimal form, nor in binary form, nor in any other digit-based representation; the number is specified by stating its square, $2$(and the convention that by $sqrt2$we mean the positive number whose square is $2$, not the negative one).
Is decimal representation arbitrary?
In everyday life, numbers are strongly associated with their decimal representations – so much so that most people who don’t usually deal with other representations of numbers identify the two and are somewhat surprised when they learn that decimal representations are just arbitrary representations and there are other, equally valid representations and numbers are an abstraction independent of any of these representations.
Is $1000 a binary number?
But to answer your question: No, being written in decimal form doesn’t just mean not being written in binary form; there are infinitely many other forms a number can be written in, including e.g. ternary, octal, hexadecimal. Writing it in decimal form means writing it out with digits from $0$to $9$like most people usually do. $1000$has four digits when written in decimal form. One usually doesn’t refer to numbers like $9.001$as four-digit numbers, perhaps because once you start writing digits after the decimal point, you could add any number of zeros, e.g. $9.0010$is the same number, so for non-integers it’s not so obvious how many digits one should count. Usually, “four-digit numbers” refers to four-digit integers. But that’s just a linguistic convention; $9.001$certainly does have four digits in its standard decimal representation without unnecessary zeros. The last digit of that representation is indeed $1$.
