- Throws MongoDB\Driver\Exception\InvalidArgumentException if `value` is not a valid decimal string.

### Examples

Example #1 MongoDB\BSON\Decimal128::__construct() example

`<?php
var_dump(new MongoDB\BSON\Decimal128(1234.5678));
var_dump(new MongoDB\BSON\Decimal128(NAN));
var_dump(new MongoDB\BSON\Decimal128(INF));
?>`

The above example will output something similar to:

    object(MongoDB\BSON\Decimal128)#1 (1) {
      ["dec"]=>
      string(9) "1234.5678"
    }
    object(MongoDB\BSON\Decimal128)#1 (1) {
      ["dec"]=>
      string(3) "NaN"
    }
    object(MongoDB\BSON\Decimal128)#1 (1) {
