I know that there's not a very simple way to pronounce decimals in Russian. Literally it would translate as "X entire ones, X tenths/hundredths/etc.", where X is feminine.

As such, 0.1 becomes ноль целых, одна десятая. 0.01 becomes ноль целых, одна сотая. If I'm not mistaken that is.

But, what if I wanted to pronounce, colloquially, a number like 0.333333333333(...), that's to say, a number with an infinite amount of decimal places?

In this situation, could I tell the numerals components individually? Like "ноль точка три три три три (...)"?

    You'd say ноль целых, три в периоде

I don't think there's any set rule, but as a native speaker I can advise the following options. First you have to know that in Russian the decimal separator is comma , (pronounced запятая, colloquially и), not period .:

0,333... – ноль и три, три, три [и так далее]...

0,333... – ноль, запятая, три, три, три [и так далее]...

More scientific way:

0,333... = 0,(3) – ноль целых и три в периоде

0,133... = 0,1(3) – ноль, запятая, один и три в периоде

  • The answers on the page russian.stackexchange.com/questions/1501/decimal-declension say decimal digits are usually pronounced in groups of two or three at a time, but 0,33333333... would not be ноль и тридцать три тридцать три и так далее?

    Well, this variant is acceptable, I think. As I said, there is no set rules regarding this. Apr 3, 2017 at 14:06
