How to Convert Int number to Double number?

Question

Using Javascript: How I can convert one number integer to Double Number Example: ``` 100 -> 100.00 ```

Accepted Answer

All numbers in JavaScript are doubles: that is, they are stored as 64-bit IEEE-754 doubles.

That is, the goal is not to get a "double": the goal is to get the string reprsentation of a number formatted as "YYY.XX". For that, consider `Number.toFixed`, for instance:

```
(100).toFixed(2)
```

The result is the string (not a "double"!) `"100.00"`. The parenthesis are required to avoid a grammar ambiguity in this case (it could also have been written as `100.0.toFixed` or `100..toFixed`), but would not be required if 100 was in a variable.

Happy coding.
