Both are correct in this case, when the digits after decimal are not too many. Otherwise, three point one four is more commonly used. For example: 3.14159, it read as "three point one four one five nine."

"it read as..." should be "it reads as ..."

In English, to read the decimal, there is NO definite rule, 3.14 read as three point one four, or three point fourteen, you can hear both way. However, when the decimal is longer, then, it is definitely will be three point one four one five nine ...

I taught Engineering in English for years, I know what I am talking about. Just stop winding this non-sense argument. In a word, people have their preference in saying this, both ways are right, if your number is 3.14.

If a simple question can generate so much traffic, I will consider to withdraw the answer to stop it.

T!, I did not say three point one hundred forty five, just three point fourteen. if it is 3.145 or 3.14159, I will definitely use three point one four five, or three point one four one five nine.

T!, your saying is really confusing the asker! If you got excited, don't spread over to other people!

I will say zero point ninety nine, or zero point nine nine. However, when there are MORE 3 digits, I will read the number one by one. Anything wrong ?

The point is to make it clear to people who listen to it !

T1, you got your point, and I am sure I am NOT wrong for only 2 digits decimal. If you think I am wrong, then I am wrong! I will not argue with you any further.
