we can do the following to convert:

```
var a = "129.13"|0, // becomes 129
var b = 11.12|0; // becomes 11
var c = "112"|0; // becomes 112
```

This seem to work but not sure if this is a standard JS feature. Does any one have any idea if this is safe to use for converting strings and decimals to integers ?

Yes, it is standard behavior. Bitwise operators only operate on integers, so they convert whatever number they're give to signed 32 bit integer.

This means that the max range is that of signed 32 bit integer minus 1, which is `2147483647`

.

```
(Math.pow(2, 32) / 2 - 1)|0; // 2147483647
(Math.pow(2, 32) / 2)|0; // -2147483648 (wrong result)
```
