Assume I have a paragraph which is :

```
var word = "Hi, I am new to this world! I am a robot, my name is RX1.456 and my age is 1.0453 days. Thats all for now, you have any qeustions?"

```

I want to find the number of sentences (in this case 3) in this for which I do :

```
word = word.toLowerCase();

word.split(/[.!?]+/).filter(Boolean).length;

```

The problem is that I do not know how to handle the dot operator when it is does not mark the end of a sentence, such as decimals. How do I handle this?
