PHP how to convert exponential number to string?

Question

I have a number stored in scientific notation

2.01421700079E + 14

I have tried using float, string, int and I cannot get

0201421700079085 from 2.01421700079E + 14

1. echo (float)$awb;
2. echo number_format($awb, 0, '', '');
3. echo (int)$awb;
4. echo (string)$awb;

printf

and friends will do this:

<?php
$awb = 2.01421700079E+14;
$str = sprintf("%d", $awb);
var_dump($str);

Output:

string(15) "201421700079000"

There is obviously not enough information in your original number to get more precision than that.
